When the teacher's son gets married, you can give him some practical and good wedding gifts, things that look tangible. After all, you are not familiar with the teacher's son, so you can't give him some small things, such as music boxes, which are not appropriate.
You can give him some high-end brand leather engraved wallets, bowls and chopsticks sets with names engraved, and antique watches. If you like collecting, you can also buy calligraphy and paintings with collection value, purple sand pictures, or a set of RMB, which are all good choices. You can also give him a mounted cross stitch, which should be very large, so that you can have face.
If he likes to drink tea, give him a set of good tea sets, preferably good tea, or just give him a few bottles of good wine. You can also give him some wedding festive items, such as quilts and sheets, and you can also give him room furnishings, such as jade cabbage, which represents blessings and wealth. Couple life dolls are very commemorative, Tang suit wedding dolls are very festive, and crystal music boxes that can be customized with wedding photos are very special and creative. Or give him something that is beneficial to health, such as: oxygen detoxification machine, massager, silk quilt. They are all great gifts.
