### Chinese: 其实原材料一样，只是大家认为贵的就是好的。
### English: In fact, just like raw materials, everyone thinks that what is expensive is good.
### Errors: There is a minor error at "just like raw". There is a minor error at "expensive". There is a minor error at "good".

### Improved English: Actually, the raw materials are the same, and people just think the goods are more expensive because they are better.
