On the whole, the old professor taught us well. If you give a gift, you can consider it according to the actual situation of the old professor, and you can start from a healthy point of view. When people get old, there will always be some minor problems, and so will old professors.

I once chose a black soil moxibustion for middle-aged and elderly people for my teacher. It is a healthy gift of moxibustion. Moxibustion has a history of thousands of years. Health care is suitable for middle-aged and elderly people. When people are old, health is very important. Teachers are easy to accept, which is good for teachers' health.

Give a gift to health, I hope it will help you.
