1. Since you have a good relationship with your teacher, you might as well give him a box of Xinyu handmade chocolates, because they are handmade and very delicate, and the packaging is also very beautiful, it is a very suitable gift. Although people say that chocolates are given to girlfriends on Valentine's Day, I bought a box of such chocolates for my female teacher last year, and she liked it very much. This is very affordable, at least it will not be ignored by the office like flowers, and this can be taken back and eaten. You can search online to see if it is suitable. The price is within my acceptable range.
2. You can consider giving your teacher some health care products, health care equipment and the like. Not the large and expensive ones. Health care products are available in ordinary supermarkets and can be bought everywhere. Equipment and the like still need to be searched online. The cheap small ones cost dozens of yuan, and the better and more upscale ones cost hundreds of yuan. It is always not as expensive as imagined. It should be within your acceptable range. Usually, whether in the office or at home, you can do a small massage when you are tired, why not.
3. Make a big cake for the teacher. You can make one at home or in a shop that specializes in making cakes by yourself. You can give it to the teacher or bring it to the class for everyone to share.
