There are too many such teachers. The interests of the whole society are suffocating. Selfish and greedy, regardless of other people's feelings, playing politics. But if we have some rights, we must show our superiority. Society is full of gambler-style lifestyle, learning style and working style. You lied to me, and I lied to you. Deceive, deceive, deceive yourself. Capitalism is exploited all over the society, but whenever you have some capital, you should try your best to exploit and squeeze it; There is no dignity or morality at all. Sadly, the society has fallen to such a state, but in any case, everyone must live bravely and live first. No matter how difficult the economic development is, how bad the environment is, how severe the employment situation is, how low and humble the salary is, you have to live, at least you still have the people who love you the most in the world. You are their only, their pride, their sustenance. Live, live, nothing else, just live. May the dead rest in peace. Perhaps only those who have read graduate students have a "painful understanding" of the last sentence and laugh at university education. What scientific research, what innovation, what research results, what papers, what patents are all floating clouds. There are a large number of patent applications every year. Why is the conversion rate so low? Pigs all know what that patent is like, except that it is fake. I still appreciate some enterprises. Although the technology is not too high, I am working hard. Only when I get the results can I be efficient. Cut the crap, that's all.
