This is a lie. This is my personal experience. He will charge you fees in various names, such as deposit, security deposit, etc. And then sign the contract for you. If you make it, he will say that your product is unqualified for various reasons. Sign the contract if you don't want to do it. According to the contract drawn up by him, it is reasonable and legal, and your deposit will belong to him. Anyone who pays by recycling or paying the manual fee is a liar.
