Lectures on Chinese studies generally attach importance to family culture, such as filial piety and kindness. Others talk about the harmony between man and nature, such as the concept of harmony between man and nature.

I suggest you start with family problems in today's society, such as elderly people living alone and left-behind children.

We can also talk about human development, which has caused environmental damage, smog, sandstorm, climate warming, ozone layer destruction and other problems.

Finally, think about what you have done. What you have done badly needs to be corrected, and you will definitely try to correct it in the future.

I hope these suggestions are helpful to you. If you have more specific questions, please continue to ask them.
