The head teacher is getting married, and you are still students, so don't waste a lot of money on wedding gifts. Consider your own ability. You can pool money together to buy the teacher an ink painting, which can be used to decorate the empty wall at home, or you can give a cross stitch, which is good.
You can give some gifts with good festive meanings, such as: real dolls, Tang suit wedding dolls, crystal music boxes that can photocopy photos, cartoon bouquets, blessing chocolates, etc.
Or give the teacher a pair of leather shoes, a set of clothes, a perfume set, or buy a good set of cosmetics, skin care products, and a set of many jewelry for the teacher's wife. You can also buy some purified water cups for the teacher to clean toxins. There is a lot of chalk dust inhaled into the lungs every day when teaching, which is definitely unhealthy. The gift is light, but the sentiment is heavy. The teacher will understand your intentions. In fact, the best gift for students to give teachers is the improvement of academic performance. If you can study hard and get good grades, this must be the best gift he has received.
