1. You have no final structure. Using templates alone, you do not have to pass the "class structure" (I mean itsMember), you can only customize the member form.2. The staff form cannot be "managed by nature 」. You can view the class template feature

  One way to solve a big problem is to break it down into many small problems. Ideally, these small problems can be quite involved.It can be solved easily and then combined to solve the big problem.If it is too large, it will be divided into
