He will like some Chinese gadgets, such as life-like pottery dolls, crystal carved ornaments, and zodiac sun jars. They are all good gifts and he will be very interested. You can also make a gift for him by yourself. If you have a girlfriend, you can also ask her for advice. Girls are more good at this.
If it doesn't seem good to just give it to your friend, you can give it to his wife. Like the crystal carved table for the two of them, just provide photos. You can also give her a customized makeup mirror. As long as his wife is happy, he will be very happy.
There are also gifts for couples, such as couple pillows, and luminous ones, which ladies will like very much. Couple slippers and couple mugs are all good gifts. You can also give some home appliances appropriately. If you can't afford the big ones, you can give small ones, such as microwave ovens, induction cookers, etc. Men are practical.
You can also give him traditional Chinese gifts, such as bright red quilts and sheets. They are all good and festive, but I don't know if your foreign friends like them. In fact, as long as you put your heart into it, no matter whether he needs the gift or not, he will understand your intention. There is no need to talk much between buddies, a few glances are enough.
