Biological science and other majors have bilingual teaching subjects (this major is a good school, at least the national key), such as biochemistry, molecular biology, genetics and so on. If you are engaged in further research in the future, it is extremely beneficial to be good at English, such as reading foreign literature.

If you are employed, it is very common to graduate from biology. You don't study without further study, but it takes a long time to join scientific research, especially for girls. If you are not very interested in the subject itself, I suggest you consider it carefully, but if you love biology, you will naturally like it. It is good to engage in scientific research and enter universities/research institutes (including foreign ones).
