In the whole field of bio-food, including food, biology, chemistry and environment, food is actually the easiest to find employment, but the starting point is relatively low and the salary is low. If the landlord doesn't like food and chemistry, see what direction he wants to develop in the future. If he wants to do scientific research after the postgraduate entrance examination, it doesn't really matter which major. If you want to study a popular major and get a job easily, I recommend electromechanical, language and economics. In fact, it is not difficult to take an interdisciplinary examination. As long as you learn English and math well, you should pay attention to the examination subjects of the major you want to take.
