How much is a piece of tofu? Yes, here it is. Is this kind of rice paper written by my brother?

See if there is a painting and calligraphy shop in your local area and ask if it can be retailed. Generally sell 10, 50, 100. It belongs to semi-ripe, suitable for beginners to learn calligraphy, unlike Sheng Xuan. If it's for practicing calligraphy, ordinary semi-cooked rice paper will do, and no special tofu publicity is needed. The price is still slightly more expensive than ordinary semi-cooked rice paper. You can look for it on Taobao.
