1, understand personality, please eat and throw a cigarette on the table. Don't smoke too well. About 400 will do.

2. If you don't eat, send some tea or a box of cigarettes, or a combination of the two. Choose a small box of tea, just one or two hundred.

3, never send wine, you can't get it, especially white wine.

4. For a female teacher, it is best to invite her out for dinner, let her bring her family and give her children a 500- 1000 red envelope. You can also send tea, especially scented tea.

If you are rich, don't think about it. Give me the expensive one. I'm in sales now, and there are very few people who are really honest.

Giving gifts pays attention to the place and form, which makes him easy to accept. In my junior year, because other students invited the teacher to dinner, the teacher selectively hung me up. This is just a suggestion. Think for yourself.
