### 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 tell the difference between good and bad, it means that you have made progress. Then come back to me to buy expensive ones, and I will make money twice.

### 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.
