A: Although there is some income, Didi is not so easy to do! On call, I often drive in the middle of the night, and I have brothers during the day. I can only drive at night, which affects my sleep and energy, so I don't approve of part-time work. And Didi is responsible! You can use your winter and summer vacations to work with your major, so that you can increase your income and practice your major in advance! what do you think? !
