### 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 the good from the bad, it shows that you have made progress. Then come buy expensive ones from me and I will make twice as much 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.
