2. Going to class without books is just like playing mahjong without money.
3. What is chemistry? Chemistry is money!
The laboratory filters dregs, while the college entrance examination filters scum.
Chemistry is not something that ordinary people can learn.
6. You look like a melon and have never studied chemistry.
7. If you don't hand in your homework, the ones behind will stand upright.
8. Do people only look at chemistry?
9. You are really retarded. You don't have these two conditions! Do you think you are a basket case?
10. What do you study and live like this for? Thanks!
