"Let's go to Drum Island, there are a lot of fish and shrimp, and there are many reefs, so you can't catch them with a net." Bo Zhu pointed ahead while rocking the oar, her posture of the oars was very beautiful, full of vitality, except for her feet nailed to the plank, the whole person was swinging with the swing of the wooden oar, the thigh muscles were tight, but the waist was very soft. Driven by her, the boat quickly left the row of boats and sailed on the sea.

"Don't look around!" Seeing Hong Tao staring at him with a smile, Bo Zhu's face turned red again.

"I'll help you row for a while, you're all sweating!" Hong Tao's face did not become thinner because of the crossing at all, and when he saw that he was punctured by others, he didn't explain, and took the initiative to lean over and take the wooden oar of Bozhu.

In less than five minutes, Hong Tao returned the wooden oar to Bo Zhu. This thing looks simple, just a push and a pull, but after getting started, whether it is pushing or pulling, there is no movement is smooth, even if Hong Tao is stronger than Bozhu, but he can't effectively row the boat, and his palm is still grinding. If you are not convinced, this is technology, it is ingenuity.

It is about five kilometers from the row of boats to Drum Island, not that the island is so far from the coastline, but it is on the west side of the row of boats, and it is really less than three kilometers from the coast. Like a perpetual motion machine, Bo Zhu shook her body unhurriedly, and when she began to gasp for air, the boat rocked to the edge of the island. Then he held on to the wooden oar, took off the headscarf, and wiped the sweat on his head, only then Hong Tao saw clearly that her hair was coiled behind her head, with a bun on one side, like two bagels.

"Little fish, little shrimp, throw the net down." Hong Tao didn't talk much nonsense, commanded the two brothers Boyu and Po Shrimp, and threw one end of the ground cage into the sea. Large stones are already tied to them, and depending on their weight, this net will sink to the bottom of the sea, and you only need to grasp the rope at the other end. When the net no longer sinks, a bamboo tube more than one meter long is tied and thrown into the water as a marker.

"It's 7 meters deep here?" When Hong Tao came, he treated this hemp rope according to the method of one meter and one knot, which is a basic skill of anglers. Whenever they came to an unfamiliar reservoir and needed to explore the depth of the water, they would tie a knot with a rope, tie a large stone to it, and row a boat to the vicinity of the nest to investigate. This one-meter distance is not blind, everyone has their own way of remembering, Hong Tao has measured it himself, and his right arm is exactly 50 centimeters from the fingertips to the elbow joint.

"Two feet and two feet......" Bo Zhu also picked up a rope, tied it to a stone and sank it, then lifted it up, measured the soaked place on the side of the ship, and gave another answer.

"Oh, it's a foot?" Hong Tao soon discovered the clue, on the wood on the inside of the ship's side, there are two marks engraved, and the distance between the marks is about half a meter, is this a foot in the Song Dynasty?

"Two feet...... How long is one meter? Bo Zhu stretched out two fingers, and then asked Hong Tao curiously about the unit of measurement.

Now, now that we have something to do, let's get to know each other about the different units of weights and measures, which is a very important question. Not only did he and Bozhu discuss together, Hong Tao also called the two children of Boyu and Po Shrimp together, and taught them little by little the relationship between one foot and one zhang, and the relationship between one meter and one centimeter. But this progress is a bit slow, the two of them are illiterate, let alone counting, there is no way to talk about addition and subtraction, the decimal is still understandable, and when it comes to the decimal system, they are confused.

But it doesn't matter, they have to wait here for an afternoon anyway, Hong Tao simply became their math teacher first. Even with Bo Zhu, first teach them to memorize multiplication formulas, and then teach them to write their names with machetes on the board of the boat, as for whether it is simplified or traditional Hong Tao doesn't care, he himself can't write traditional characters, make do with it.

The more ignorant a person is, the higher the thirst for knowledge. Although Bo Zhu, Bo Yu and Po Shrimp don't say it, they still attach great importance to being able to go to school and read and write, so they don't care whether Hong Tao teaches it correctly or not, they all sit on the board of the boat and listen to Hong Tao's lectures in a regular manner, and no one says a word more, which is very honest. Then Hong Tao came up with a few targeted questions, for example, a fish sells for three cents, and ten fish sell for a few cents? What about twenty? What about thirty? If there are big and small of these fish, the big ones sell for five cents, the small ones sell for three cents, and three of the ten fish are big and seven are small, how much can they be sold for?

These simple arithmetic problems made the three of them dizzy, counting their toes and fingers, and finally they were in a hurry to count the three of them together, and they were always unable to count. But when the multiplication formula taught by Hong Tao was calculated, they were immediately happy, Bo Yu stood behind Hong Tao, holding a broken sail to the teacher to file the sun, and Bo Shrimp held a coarse porcelain bowl, respectfully waiting for the teacher to drink water when he hurriedly handed it over, Bo Zhu was not idle, she washed the headscarf with seawater and washed, as long as Hong Tao wiped the sweat, she immediately sent the headscarf. The three of them were each busy, so they didn't delay their studies, and the afternoon passed in a blink of an eye, and everyone was still on the boat to memorize the multiplication formula, and the sun didn't know that it was setting in the west.

"Ah Zhu, it's weird again!" Suddenly, a shout rang out from the side of the boat, startling the four people on board.

"Grandpa! It's all your fault, I forgot ...... again" Ah Zhu was reciting the mantra, and finally passed five, and was just about to hit six, but now she forgot everything, and in a hurry, she picked up her headscarf and threw it towards the boat next to her.

"Grandpa, I can write my name, Uncle Tao taught me, come and see!" When Boyu and Po Shrimp saw their father, they also wanted to show off their academic performance, but unfortunately they couldn't pick up the board, so they jumped straight up.

"Fu Bo, Huang Bo...... Pander to...... Grandpa! Hong Tao turned around and saw that several small boats from Bo Fu, Huang Hai, and Chen Mingen had returned, and the previous title was smooth, but it was still a little rusty to call Grandpa.

"Hehehe, I'll look at what you wrote, huh...... Boyu, that's right! Lake...... Shrimp? This is the Australian word for shrimp? Chen Mingen heard Hong Tao call him Grandpa, smiled very kindly, brought the boat over, leaned on the boat and looked at the words on the board, some he knew, and some were different.

"We also learned Chinese characters at first, but later for the sake of simplicity, we simplified the strokes a lot, and the original characters were not learned by young people, and I didn't." Hong Tao simply explained the principle of simplifying words, believe it or not, don't go to the exam anyway, it doesn't matter.
