### Chinese: 还有你想那么多的厂家每年的广告费都要几千万甚至是几个亿，这个费用何来？
### English: Also, you think so many manufacturers spend tens of millions or even hundreds of millions of dollars in advertising fees every year. Where does this cost come from?
### Errors: There is a major error at "Also". There is a major error at "you think so many manufacturers spend". There is a major error at "dollars". There is a minor error at "cost".

### Improved English: Just think about where the tens of millions or even hundreds of millions yuan advertising fee of the manufacturers come from every year.
