### Chinese: 你想着没什么损失，还能赚钱，就签下了合同。
### English: If you don't think about losing anything and still make money, you have signed a contract.
### Errors: There is a major error at "If you don". There is a major error at "t think about losing anything and still make". There is a minor error at "have".

### Improved English: You signed the contract since there would not be any loss and you could make money.
