不难理解，要拍什么应该提前说好签订合同，不是等到拍摄的时候才懂得要被逼迫被胁迫拍摄合同以外的东西
It's easy to understand what you're going to do. You're going to have to sign a contract in advance. You're not going to have to wait until you're going to do it. You're going to have to be forced into filming something that's not part of the contract.
