Only two points:
1 Pay attention to the contract content of the brand you represent, and be sure to read it carefully. If there is something unacceptable, let's see if the other party can modify it properly. Otherwise, there will be problems later, mainly small problems of money, and finally legal problems may arise (I am talking about situations that may be serious).
2. Ask the legal personnel about the problems they need to pay attention to and encounter (don't go to any law firm casually, the problems are simple and expensive, but go to the legal aid website or the local legal aid center to find out), mainly referring to the contract problems.
