I wish you a safe and smooth life in the future. When you encounter difficulties, you can also face them and succeed. If you have any questions about people you don't understand, you can keep asking. Don't feel embarrassed or worried. We have always been the backstage of your most loyal friends. In reality, you can tell me in detail about illegal infringement and unsatisfactory things. We have always provided the most reliable judicial answers, help and help.

There are a thousand hamlets in a thousand people. In any case, there are no two identical leaves in the world. Everyone has different views and opinions, and everyone will have different criteria for judging the same thing. My answer may not be the most standard and correct, but I also hope to give you some help and get your approval. Thank you!
