Thank you letter for doctoral dissertation: When I was born, it was a snowy night, my father made a pile of firewood next to the bed, and my mother lay on the bed in the corner of the broken house that leaked around, gritted her teeth, and gave birth to me. Twenty-seven years later, also in the middle of a snowy night, I finished my doctoral thesis. When I finished typing the last word, I stood up, opened the curtains, opened the window, and the noisy and noisy world during the day turned white, and it made people feel clean.

I went from the time I entered the university to the time I graduated with my Ph.D. for a full ten years. During these ten years, I was in a state of astonishment. Ten years ago, I was 4250px, ten years later, I am still 4250px, ten years ago, I weighed 60kg, ten years later, I still weigh 60kg, ten years ago, I had nothing, ten years later, I still have nothing. Ten years ago, my eyes were bright and bright, but ten years later, when I took off my glasses, I couldn't see how many fingers I had; ten years ago, my voice was loud and clear, and ten years later, I was already suffering from chronic laryngitis and my voice was hoarse; ten years ago, I was full of ambition, pointing out the country, and inspiring words; ten years later, my heart was like water, and I only wanted food and clothing; of course, I also got something. Ten years ago, I was the son of a farmer, ten years later, I became a doctor; ten years ago, I only knew how to chop wood, farm, mow grass, and herd cattle, and ten years later, I have become a compound talent who understands mechanics, finance, and management; but if you ask me what is the biggest growth in the past ten years, I will tell you: ten years ago, I was seventeen, ten years later, I am twenty-seven.

In the past ten years, what have I longed for and pursued the most? Is it knowledge? No. Is it a beauty? No. It's money. In my mind, money is the kind of coins that are one piece and a dime, and I have searched them countless times, the purpose is to buy a pack of instant noodles and have a dinner, and I can't look too carefully when looking for it, too carefully, and next time I won't have it. Sometimes, when I don't know where my next meal is, I think if only some money could fall from the sky, and I look up and see the yellowed leaves falling one by one, and I think I can pick up some money on the ground, and I look down and see some bread wrappers and some bamboo skewers for lamb skewers. I've never seen money fall from the sky, and I've never picked up money on the ground, so I don't believe in the existence of a god, so I don't have faith. I would like to express my heartfelt gratitude to my mentor for his gentle teachings and careful care, and for his meticulous care in my life and study during my three years of Ph.D. He may be the only teacher I have known my name in my ten years of university life, and I am grateful for his meticulous guidance even though he has been responsible for guiding more than 20 students. My mentor's guidance and influence on me are so great that I can't express it enough, and the little achievements I have made are all the result of my mentor's hard work. The teacher's international vision, cutting-edge and quintessential academic attainments, and rigorous and diligent academic style have all made me never forget and profoundly influenced my future work and life.

I would like to express my heartfelt gratitude to my elderly parents, who have been unfaithful and unfilial during these 10 years and have not allowed them to live a happy life. They kept supporting, caring and encouraging me. I often ask "Are you short of money?" so I believe in family affection. I never wanted their money, I didn't want to see a hundred dollars, I thought of hundreds of eggs, hundreds of loads of hogweed, thousands of red bricks.

I would like to express my heartfelt gratitude to my five older sisters for accompanying me through a happy childhood. Their beautiful and innocent girlhood aroused my respect and desire for the opposite sex. During the ten years of my study, they kept calling me, asking me about my health, my life, asking me to eat more, and sending me money, but I kept refusing them. In the past ten years, they have lived an inhuman life in GD's woolen mills and garment factories. I don't want to see the kind of thing that is bought for blood, flesh, life, and youth. Ten years ago, they were still flowers, and ten years later, when they appeared in front of me, I no longer believed that they were my sisters.

Finally, I would like to thank my girlfriend, who has lived in SH and HZ, the two most developed cities in China, for 5 years with a total monthly income of less than 600 yuan. In the past 5 years, I have not bought her a decent gift, and she has sent me countless times when I am in my prime to save money for her frugality, so I can finish my studies, so I believe in love. I can't understand that she can still help me with a monthly income of 275 yuan, maybe her slender, slender figure is the best answer.

The girlfriend of the doctoral student has something to say: before I met my boyfriend, my admiration for the doctoral students was like a surging river, I used to think that they were the pride of their hometown, the elite of the country, like the gods on the mountain, devoted to scientific research, at ease, very different from us mortals. However, I now find that the PhD students are a particularly "disadvantaged group".

A few days ago, I heard from my boyfriend that his brother in the bedroom next door had broken up with his girlfriend, and his girlfriend's parents did not agree to marry their daughter to him who had no house. My boyfriend's roommate also broke up with his girlfriend who had been in love for 2 or 3 years, the reason was still the house, the money! They were already getting married, his girlfriend was working in his hometown, and he was going to come to SH after getting married, she asked to buy a house in SH, and his current financial situation couldn't buy it, so he quarreled ~~~ Quarreled to the point, divided it~~~ Divided, just like that, because of the house, money, house! I heard that the doctor brother drank every day, and he couldn't help crying at night.

I'm a girl, and I can understand girls and their parents. Parents hope that their daughters will marry someone with better conditions, so that their daughters can suffer less and suffer less. I also once cried fiercely because my boyfriend's current economic conditions are not good: why are other girls getting married, having romantic weddings, diamond rings, houses and cars. And we, if we want to have a wedding, we have to go to the four sides to borrow money, not to mention the house and car, why? I feel wronged, I am no worse than other girls, why is my life like this?!!

My boyfriend is also very uncomfortable, dumb eats coptis, and he can't say what he suffers. Ten years of cold window, he was admitted to Jiaotong University from the countryside, graduate school, doctoral study, in his hometown he is a role model for younger students, is regarded as a genius, is the pride of his hometown. In school, he concentrated on scientific research and won many praises for his earnest and hard-working achievements. But he couldn't stop my tears of grievance, materially, he can't give anything now, and he doesn't understand why he thinks he is very good, but his life is like this. The school's subsidies can only basically ensure their own food and clothing. This year's birthday present was a rose gold necklace, I was happy and distressed, he saved for a long time in order to give me a gift.

He didn't have any money, but was he wrong??! no!! He worked hard every day, studying and working hard. Am I at fault?! I understand his situation and his difficulties very well, but I just want to cry, I just can't stop crying. In this material society, I admit that I am a little impetuous, and I also want to be as indifferent to fame and fortune as a god, but sometimes, really, so sad. ......Why? I remember when I asked my boyfriend why he applied for the mechanical examination of Jiaotong University at that time, he said that he was very fond of military affairs in high school, especially liked to read fighter planes and warships in military magazines, and he dreamed of becoming an expert in building aircraft carriers in China.

Later, I asked him why he was studying for a doctorate, and said that he hoped to live a better life in the future, but he knew that it was like this now, so it was better to come out to work as an undergraduate, and like those undergraduate students, they had already lived a good life. I would like to tell my younger students, especially those of you: if your family is not very wealthy, please think carefully before deciding whether to pursue a doctorate and engage in scientific research, no matter how suitable you are for scientific research, no matter how passionate you are to dedicate yourself to science. Because, the pressure from life and emotions is very willing to extinguish the flame of your passion.

Ph.D., it's very difficult to read, many Ph.D. students have gray hair before the age of 30, and their hair decreases with more thinking; moreover, basically, at least until the year of study, your little subsidy is only enough for your own food and clothing, and your parents are providing for you to go to college, and you can't take a break after grad school, they think that you haven't worked yet, and they want to help you save money to marry a daughter-in-law (my boyfriend's parents are nearly sixty years old, and they have planted a lot of vegetables to sell, and you can think of the vegetables in the market that they have planted, no matter how hot the day is, they are busy in the fields. In order to occupy a good stall, he got up at 2 o'clock in the morning every morning to go to the city to sell vegetables, and he didn't listen to how to persuade them not to go because he was tired and bitter, just because he didn't have a job yet).

Another thing that makes you sad is that your classmates' children can go to soy sauce, you have not had a girlfriend for several years after the age of late marriage, and if you have a girlfriend, the situation is even worse: the pressure is just from feeling sorry for your parents, and now your girlfriend is under another layer of pressure. Even if she is very reasonable, gentle and considerate, kind and simple, not noisy or complaining at all, you will be stressed. A responsible man will try his best to make his lover live a better life, and you basically can't give her anything now, and even, the salary is less than half of hers.

The worst part is that you were stabbed while you were struggling to move forward under great pressure: she left you. Everyone thinks that there is a bright future after graduating from the doctorate, and yes, after graduation, you are considered to be a fragrant bun, and maybe it will be easy to marry a big beauty. However, how many people have been able to survive the pain of the past few years? Emotional wounds, hearts that have been stabbed with knives, and scars for the rest of their lives. I probably know why there is news of Ph.D. suicide in famous universities almost every year, it is definitely not because of which algorithm is difficult and cannot be pushed, but because the thoughts and feelings have entered a dead end, and they are so depressed by all parties that they can't stand it and can't solve it.

They have high IQs and are elites in a certain field of science, but emotionally they need too much support to withstand too many blows. In fact, I think they are a special "vulnerable group". We all know the need for a gold tower: physiological, safe, social, respectful, and self-actualized. I found that our hard-working PhD students have much less physical and social needs than the average person of the same age. I hope that the leaders of the Ministry of Education will take the time to write those 44 Chinese characters better, and at the same time, take a moment to care about the doctors we have spent 20 years training.

They don't expect doctoral students to have a good life, they are mostly used to being poor, but they hope that life will not put too much pressure on them and make them share too much heart. I hope that I don't have to be overstretched too often, I can buy some supplements and two clothes for my parents during the Chinese New Year, and I don't have to think about how to save money in the next few months when my classmates get married and give red envelopes...... Let them devote themselves to scientific research, and perhaps, we still have the possibility of winning the Nobel Prize. Finally, I have something to say to my sisters: Now there is a popular saying in society "Who will marry you if you don't have a house or a car?", in fact, there is no need for us to follow the crowd.

I used to think about what you need most when you're old? Not a fancy car, of course - it's someone who holds your hand and walks with you. When you want to leave this world, what is the most nostalgic? Of course, it won't be a mansion -- it's the person you love! If you meet someone, he loves you, you love him, you have a suitable personality, you know that you won't change your mind, then -- marry him! No matter how many rooms he has, how much money he has saved, how many acres of land at home, and how many cows in the field~~~ Believe me, you will be happy for a lifetime!
