Although Hong Kong is a family with our mainland, there are still differences in the social environment. The characteristics of our mainland, especially the things handed down by our ancestors, are very good. You can choose:
1. The four treasures of the study, porcelain, calligraphy, and Chinese paintings. If these things can be collected, it will be even better.
2. For example, Chinese knots; silk scarves, handkerchiefs, embroidery, and paper-cuts with Chinese characteristics; facial makeup, ancient fans, small kites, etc., these things are small, but they can also represent our ancient Chinese culture. Your friends may like them.
3. Jade or copper coins, these things are also very good, especially jade. If you can choose well, a piece of raw stone can make a lot of jewelry. 4. Tea, tea sets. I think it is also good to give a set of tea sets. Our tea culture is relatively rich, and many famous teas are produced in our mainland. You can bring some to your friends to taste.
