"Mom, dad wants to catch a lot of beautiful fish for Nannan, Mom, when the time comes, give some to Mom, okay?" Before Zhao Chaogang walked into Li Liping, Nannan, who was originally holding Zhao Chaogang's hand, ran directly to Li Liping's side and showed her.

Children like to show off like this, as long as there are good things, he can't help but show the good things to his relatives or other children. As soon as those people showed envious expressions on their faces, the little child would be happy in his heart, and this is exactly the state of the girl now.

As a mother, Li Liping certainly understands the mentality of children, so she said very cooperatively: "Oh, then my mother is going to envy the dead girl, my father hasn't caught any fish for my mother, nannan, is it okay for my mother to let my father catch fish for my mother?"

"No, Dad can only catch fish for Nan Nan now, and if Mom wants Dad to help catch fish, she has to wait for the next time. When she heard that her mother also wanted her father to help her catch fish, she was anxious.

"Woo woo woo...... , Nan Nan didn't even want to help her mother catch the fish, her mother was sad!" Li Liping was very involved in the play, and directly pretended to be crying, which made the Nan Nan on the side anxious immediately, she didn't want her mother to cry.

"Okay, okay, let your father go to your mother, don't cry, Mom, okay?"

Seeing Li Liping 'crying', the girl on the side immediately panicked, and hurriedly let her father out, so that Li Liping, who was pretending to cry, was very warm in her heart, and she was really her own intimate padded jacket!

"Hahaha....... Nan. Mom is joking with you, how can Mom rob Dad with Nannan, Nannan is Mom's most precious baby. Where will mom snatch the baby's things, well....... Li Liping happily hugged Nan Nan directly and kissed Nan Nan on the face.

"Giggle...... , Mom, don't ......!" Li Liping's kiss made Nan Nan feel a little itchy, so Nan Nan laughed at the same time. While she began to dodge Li Liping's kiss, the beach was instantly filled with the ...... of affection between mother and daughter!

"Chao Gang, when you go into the water. Be careful, although your strength is very strong, but no matter how strong your strength is. In the face of the power of nature. Nor is it an opponent. Chao Gang, you and Jingjing don't rely on strong strength, just go to some very deep and dangerous places under the sea to have some adventures, you still dive into the water here in the shallows.

Anyway, talking about the beautiful scenery seen in diving, it is more beautiful and interesting than what you see in the deep sea, so this time I dived. You can just dive in the shallows, so you don't have to worry. Got it?"

After playing with Nannan for a while, Li Liping began to tell Zhao Chaogang, who was changing clothes, for Zhao Chaogang and Liu Jingjing to go diving, Li Liping did not object, but she needed to be safe, and she couldn't rely on her strong strength, so she went to those very dangerous deep seas to play diving adventures or something.

As a woman and a wife, Li Liping definitely doesn't want her husband to go on an adventure or anything. A home doesn't need any dangerous passion, she needs just plain warmth.

"Don't worry, Pingping, we won't go to the deep sea to play any dangerous adventure games, we just dive in the shallow sea here and come back. ”

Although Zhao Chaogang doesn't matter if he goes to dive in the deep sea, after all, Zhao Chaogang is the master of the martial arts secret realm, and in the martial arts secret realm, Zhao Chaogang can do whatever he wants, but she doesn't know these things Pingping yet.

Besides, Pingping said this, in fact, he cared about himself, as Pingping's husband, where would Zhao Chaogang ignore Pingping's concern, so even if Zhao Chaogang knew that no matter how deep he dived into the water, there would be no danger, Zhao Chaogang still obeyed Pingping's persuasion very obediently, and just dived into the water on the shallow sea.

"Pingping, this time you are pregnant, so you can't go diving in the sea, next time we wait until Pingping gives birth to a child, we will come to Fairy Beach again, and when the time comes, I will accompany you to the sea to dive." Pingping, okay?"

Zhao Chaogang is a bowl of water at home, this time Pingping can't go diving due to physical reasons, then he will take Pingping to dive next time, this is Zhao Chaogang's compensation for Li Liping.

"Well, let's wait until I give birth to a child!" Li Liping said happily, Zhao Chaogang can care about his own thoughts, which makes Li Liping's heart very warm, husband and wife get along with each other, they should care for each other and take care of each other, so that the relationship between husband and wife will be more lasting and sweeter!

"Chaogang, for me, the most important thing now is to let the baby in the belly be born safely, I don't care much about other things, and, these days I am busy with the wedding, you are tired enough, go diving to relax yourself, it is also a good thing, you don't have to worry about it on my side, I will take good care of myself, you go diving!" Li Liping is still so virtuous, and she only cares about Zhao Chaogang in her heart.

"Well, Pingping, that's going to be with you now, I'm going to dive with Jingjing now. Pingping, I'll be back soon. After Zhao Chaogang said this, he turned to face Nannan, and then said: "Nannan, now you are a sister, so you have to protect your mother and the younger brother in your mother's womb here, this is your responsibility as a sister, do you know?"

Before leaving, Zhao Chaogang once again told Nannan, a child like Nannan is the most playful, and likes to imitate others the most, if Zhao Chaogang and they dive, Nannan also followed the water, it would be dangerous, so, before Zhao Chaogang left now, he once again told Nannan to protect his mother and younger brother, this is to let Nannan stay by Pingping's side with peace of mind.

For children, sometimes direct persuasion is often not as good as indirect persuasion or persuasion with the nature of games, Zhao Chaogang has done a good job in understanding the mentality of children, and his father is very competent.

"Well, Dad, don't worry. Nan Nan will protect her mother, and the younger brother in her mother's belly, Nan Nan is now a sister. It's an adult. Nan Nan promised Zhao Chaogang with an adult-like face, it can be seen that Zhao Chaogang's words just now are indeed very effective.

"Yes, our sister is now a sister. Zhao Chaogang touched Nannan's head, and then continued: "Sister Nannan, my mother and younger brother will be handed over to you for protection, and Dad will now go and catch the fish for Nannan." ”

"Hmm. Dad, you want a lot of good-looking fish!" said "Babyshit" said greedily. And he also opened his hands and made a big gesture to show that he wanted a lot, a lot of fish. Children are so naïve.

"Got it. Dad will catch a lot of fish for the girl. Zhao Chaogang stood up as he spoke, and then said to Li Liping: "Then, Pingping, I'm going now." ”

"Well, be careful......!"

Diving is an activity that involves going below the surface with or without professional tools for the purpose of underwater surveys, salvage, repairs, and underwater works. Later, diving gradually developed into a leisure sport with underwater activities as the main content, so as to achieve the purpose of physical exercise and leisure entertainment, and was widely loved by the public.

After entering the Internet era, with the continuous popularization of network applications. The public has given diving a new meaning, that is, without the knowledge of others. Privately watching shared messages or comments without actively revealing one's identity, posting information, or replying to others' messages.

Geographically, however, diving also refers to groundwater buried above the first aquifer, which is increasingly being used in networks.

As early as 2,800 years ago, during the heyday of Mesopota culture, the army of the Azriya Empire used sheepskin bags to attack enemy troops from the water, which may be the ancestor of diving.

1,700 years ago, in the Chinese history book "The Biography of Wei Zhiwei", there was already a description of a seaside fisherman diving and fishing in the sea. In 1720, an Englishman successfully salvaged to a depth of 20 meters using a custom-made wooden barrel.

The predecessor of today's professional diving is the mechanical diving invented by Golmon Bessey of the United Kingdom 160 years ago, that is, helmet diving, which first appeared in Japan in 1854.

In 1924, the "mask submersible", which used glass as diving goggles and pumps to draw air from the surface, was the predecessor of scuba diving equipment.

In the same year, the Japanese shocked the world by diving 70 meters to the bottom of the Mediterranean Sea using a mask submersible and successfully scooping up the gold nuggets from the sunken ship Yasaka.

During the Second World War, a special military "air cover submersible" was developed, using a closed-circulation device with air cylinders.

At the end of World War II, Lanxi developed an open "air submersible", which was very popular in Europe and the United States around 1945. In recent years, due to the progress of diving equipment, diving sports have flourished, and more and more people have devoted themselves to diving and liking diving sports.

With the sport of diving taking the world by storm, stepping into the underwater world is no longer a fairytale wish, but a romance that will surprise you. You don't need to learn to dive beforehand to feel the novelty of diving in real water, imagine that when you dive into the cool and clear water, the sunlight is refracted by the water into countless stars, constantly twinkling and shining in front of your eyes.

When the colorful fish snuggle up affectionately, you will be happy to feel that you are in a wonderful new world, and enjoy the colorful and diverse underwater creatures;

As a string of bubbles floats happily past your ears, you will be amazed to find that you are easily flapping your flippers and floating freely in the water, truly appreciating the wonder, romance, ease and happiness of the underwater world.

Nowadays, diving is becoming more and more popular with the public, so soon, there are many diving clubs in the society to teach people to dive. Each club usually arranges the training of students in the swimming pool of a star-rated hotel, and after mastering the basic diving skills and obtaining the assessment certificate, they organize a trip to the coastal city to experience the fun of natural diving.

The benefit of diving is not only the great enjoyment that the strange world in the water brings to people's spirits, but more importantly, it can improve and improve the cardiopulmonary function of the human body, which is very important in the United States and Japan. Diving has even been used as an adjunct to the treatment of cancer;

According to scientific evidence, the balanced pressure of water on the human body helps blood circulation, and prolonged oxygen inhalation underwater can effectively kill cancer cells. It also inhibits the spread of cancer cells, but because of the high cost of diving, the average person cannot afford it.

Although the cost of basic training is generally only about two or three thousand, the equipment and travel expenses that come one after another are not digestible to everyone. A good set of equipment, ordinary 20,000 or 30,000, and high-level 100,000.

If you want to go to a good natural sea area, there are monkey countries and demon countries nearby. As far away as Australia, the Red Sea, etc., such a trip is for most people. It's just a dream.

There are two types of equipment worn and worn by divers when they enter the water: heavy and light.

Heavy equipment includes helmets, gas pipes, communication cables, telephones, diving suits, lead pressure and lead-soled diving shoes, etc., while light equipment has masks (light helmets are also used), gas tubes, communication cables, telephones, emergency gas cylinders, diving suits, waist lead, boots and fins, etc.

When working in the water with heavy diving equipment, you must step on the bottom or the real thing, or grasp the cable by hand, and cannot work in levitation. and drifting (i.e., at the bottom of the water due to excess gas in the wetsuit. Loss of control and sudden rapid ascent) is dangerous, so heavy diving equipment has gradually been replaced by light equipment.

For an object placed in water, the amount of buoyancy it experiences is equal to the weight of the amount of water it displaces. If the weight of the discharged water is greater than the weight of the object itself, the object will float on the surface of the water, and we call it positive buoyancy.

Otherwise, it sinks, which is called negative buoyancy. If the weight of the water discharged by the object is equal to the weight of the object itself, the object will be suspended in the water and will reach neutral buoyancy.

While diving. It is very important to learn how to control the amount of buoyancy on the surface and underwater. For example, when resting on the surface of the water, positive buoyancy can save the body. Underwater, however, you need to maintain neutral buoyancy most of the time to allow you to swim freely and easily, maintain good visibility, and avoid harming you and the fragile creatures in the water.

The diver can adjust the amount of buoyancy by means of guò counterweights, buoyancy adjustment devices (BC) and the depth of breathing.

Necessary learning before diving in the sea: including how to use snorkels and regulators, how to rest on the surface, how to deal with emergencies, etc.

Preparation before entering the water is very important. Check whether the equipment is functioning properly by yourself, and check each other again.

Position to enter the water: Vertical diving - the water depth should be more than 1.5 meters, with both feet open in front and back, holding the mask with one hand and the air tank strap with the other. Entering the water with your back to sit - sit on the boat facing inwards and enter the water with your back on your back. Frontal seated entry into the water - for beginners. Sideways into the water - then float on the dinghy and roll into the water.

Dive: B.C. (Buoyancy Moderator) method - when using a buoyancy regulator, with a counterweight belt, the head and feet of the dive. Do not use B.C-head under foot.

Ascent: Control the ascent speed to within 18 meters per minute, simply put, do not exceed the rising speed of the air bubbles you exhale, do not stop breathing, look up at the water surface when ascending, you can stretch out your right hand to specify the direction, pay attention to the back, and slowly rotate the body.

In addition, the following patients are not suitable for diving. People with colds, nervous disorders, ear and nose diseases, heart disease, high (low) blood pressure, drunkenness, and diabetes should not go into the sea to dive.

Precautions for diving: 1. Keep communicationIn the process of diving, communication with divers and companions should be done well. Effective communication is a better guarantee for the diving process.

In foreign countries, not all divers are a simple model of one or two belts, and some popular diving spots often have a person with a dozen people diving, so the rules of the team must be strictly observed, even if there is an emergency situation underwater, you can find a way to solve it in time.

2. Do not act alone to dive in unfamiliar waters, do not act alone, because there may be many hidden dangers if you do not understand the sea area, and if you act alone, it is easy to have irreversible consequences.

At the same time, if you are underwater with your companion and suddenly find that your companion is missing, you are generally only allowed to wait underwater or look for one minute before leaving.

3. Don't touch anything you see on the bottom of the sea, the oncoming sea turtles may make you want to get up close, and schools of corals and cute tropical fish will make you curious to reach out and touch them, but this behavior is basically not allowed. Destroying the environment and harmony of this sea, maybe you won't be able to see these amazing species next time you come back.

⒋。 Other matters: first, adhere to the principle of two people walking together, follow the leader closely, second, wear a life jacket, third, wear a weight belt last, fourth, do not use earplugs, fifth, remove the water in the mask, sixth, do not overbreathe, seventh, remove the fins, mask, and snorkel after completely leaving the water.

Some common sense to pay attention to when diving:

Cramps: Cramps can occur if you're nervous, if the water is too cold, or if you've been in the water for too long. Preparation activities before entering the water should be sufficient, and the time in the water should not be too long. If you have cramps, don't panic.

For example, if you have toe cramps, bend your legs immediately and pull your toes apart and straighten them. Calf cramps, first take a breath, lie on your back on the water, hold your toes with your hands, and push your calves forward vigorously to stretch and relax the contracted muscles; When your fingers cramp, clench your hands into fists and open them vigorously, and this is repeated to liberate you.

Dizziness and brain swelling: The main reason is that the diving time is too long, the blood collects in the lower limbs, cerebral ischemia, the body's energy consumption is large, and the body is overtired. Immediately go ashore to rest, keep your whole body warm, and drink some light sugar and salt water.

Nausea, vomiting: This is the case when you choke on dirty water through your nose. Hurry ashore, and then press the navel and Neiguan acupoints with your fingers, and if you have Rendan, you can also contain a pill. To prevent enteritis, you can also eat a few cloves of raw garlic.

Itchy and rashy skin: caused by major skin allergies. Immediately ashore. Take a dose of oxysmine or chlorpheniramine and it will get better soon.

Itchy and sore eyes: may be caused by unclean water. Immediately after disembarking, the eyes should be rinsed with clean light salt water, then the eyes should be spotted with chloramphenicol or erythromycin eye drops, and it is best to apply a warm compress before going to bed.

Headache: This may be caused by chronic rhinitis, choking or cold, or temporary cerebral vasospasm that causes insufficient blood supply. At this time, you should go ashore quickly, use your thumb to rub the Baihui, Sun and Lie Missing points on the top of your head, then apply a hot towel to your head, and drink a glass of hot boiled water, you can get better.

Abdominal pain and bloating: Abdominal pain and bloating can occur just after eating or diving on an empty stomach. At this time, you should go ashore and lie on your back, press the middle courtyard, the upper courtyard or Zusanli with the tip of your hallux, take 3 to 5 ml of ten drops of water orally at the same time, and apply a hot hand towel to your abdomen.

Earache, tinnitus: It may be filling the ears with water or choking on the nose, and the drainage methods are:

(1) Tilt your head towards the side of your ear where water has entered, pull the earlobe firmly, and jump on one foot with the same leg.

(2) Aim the palm of your hand at the ear canal, use your hand to block the ear tightly, tilt your head to the left when the water enters the left ear, and then quickly pull your hand away, and the water will be sucked out.

(3) Use a disinfectant swab to suck the water out of the ear canal.

It can be said that diving in the sea is actually very difficult, and if you want to dive safely in the sea, it is best to go to some professional institutions to learn, so that it is safer.

Of course, for Zhao Chaogang and Liu Jingjing, these problems are completely small CASS, Zhao Chaogang is now a cultivator in the middle stage of foundation building, and Liu Jingjing is now a cultivator at the first level of Qi refining, diving in the shallow sea is a completely trivial matter.
