The better gifts for your teacher are sun jars, calligraphy and paintings, etc. Young teachers also like novel things. For example, sun jars are more distinctive gifts. You can also hand-paint patterns on them or write on them. In short, it breaks through the original craftsmanship and makes the gift more meaningful.
Male teachers should also prefer practical gifts. Like razors, and better men's shoulder bags. If your teacher is also a person who likes sports, you can also give him better basketballs, footballs, or sportswear and other gifts.
On Teacher's Day, we mostly send flowers. I don't know if you have any other customs. In Shandong, we send carnations and chocolates. You can also send flowers to male teachers. Some teachers also prefer ornaments, such as car pendants, or more artistic decorations at home. You can give root carvings or calligraphy and paintings hanging on the wall.
