### 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 progressed. When the time comes, you will come back to me to buy expensive ones, and I will earn 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.
