My classmate graduated from the Mathematics Department of Normal University on October 20 14, thinking that Shanghai would be a junior high school mathematics teacher. The basic salary is 4000, and the class fee plus bonus is more than 2000. There are also social security and provident fund. Getting it in a month is more than 5000. The annual salary in the first year is about 70 thousand. The salary of graduate students should be higher than his, not lower than the annual salary of 70 thousand.
