How much is it to be a librarian in Tsinghua University? 1 month? (2003-2005)

It is estimated that he is a contract system, not a career system. I wonder how much it costs. Money is rarely real anyway. This year's graduate students just came in, that is, in 2000, insurance and provident fund will be deducted, which is more than 1000.

There are many poor and rich people in Beijing, and many people earn two or three thousand yuan a month. Most of them are ordinary people. Let's just say that my classmate worked in a state organ for a month and provided dormitories for more than 2,000 units, but the conditions were poor. Some people say that there are almost no bonuses and gray income, and not everyone is so greedy.
