Dear, since you are going to give it to foreign friends, then as long as it is Chinese, it will have local characteristics for them. You don't need to consider the region. Just choose some small gifts with national characteristics for them.
First, Peking Opera art is the quintessence of China and the treasure of national culture. In the eyes of foreigners, Peking Opera is mysterious and attractive. I recommend you a clay Peking Opera figurine that perfectly combines Peking Opera culture and clay sculpture art. The colors are bright and the image is lifelike. Foreign friends will be ecstatic when they see it.
Second, blue and white porcelain is also a unique branch of art and culture in China. Blue and white porcelain is extremely beautiful and cannot be copied in the eyes of foreigners. Although a delicate and small blue and white porcelain bookmark is not expensive, I believe that this is the best gift in the eyes of foreigners.
Foreigners do not produce tea. They are used to drinking coffee. However, with the cultural exchanges in society, more and more foreigners have fallen in love with China's tea culture and Chinese tea. Send them a few boxes of authentic West Lake Longjing, and they will definitely like it.
