1. First of all, I want to express my gratitude and appreciation to Han Yu and evaluate his thoughts and viewpoints. Specifically, you can affirm and respond to Han Yu's remarks by saying "I deeply feel your true feelings", "I appreciate your opinions" and "your criticisms and suggestions are very pertinent".

Secondly, we should respond to the questions raised by Han Yu in his letter. I classify according to Han Yu's various viewpoints or thoughts, list my own opinions respectively, and give some concrete measures or schemes.

3. Finally, you need to summarize the whole reply and sign or seal it yourself. At the same time, you can also add some greetings appropriately.
