### Chinese: 等你真的能分辨好坏，说明你进步了，到时候再来我这里买贵的，我赚两次钱。
### English: As soon as you can really distinguish between good and bad, showing that you have progressed, at the time to come back to me here to buy <v>expensive</v>, I earn twice the money.

### Improved English: If you can tell the difference, it means you have made improvement; then you can come here to buy the expensive ones and I will make money twice.
