Is it appropriate to send brushes and rice paper to elders?

As for Four Treasures of the Study's gift, it is definitely to send some high-end goods, otherwise it is impossible to get it. For people who like calligraphy, a good Four Treasures of the Study is a favorite gift. Of course, if he collects a better one himself, you will be carrying coals to Newcastle. But if you are also a calligraphy lover, the distance will undoubtedly be closer. Of course, good relations are also necessary. You must make the best impression on her parents and buy some supplements for her mother. It's almost enough. In short, you should investigate each other's hobbies first, and then give them their favorite gifts. I believe this is harmful.
