### 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: When you can really distinguish between good and bad, it shows that you have improved, and when the time comes<v> to</v> come to me to buy expensive ones, I will make money twice.
### Errors: There is a major fluency/grammar error at "to" within <v></v>.

### 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.
