Upstairs is also a saying, but the present gift inkstone is not practical, but scientific in nature, and all kinds of themes are carefully created by masters, including commercial themes, such as three-legged golden toad, making a fortune and so on. It is not only novel and unique, but also shows the details of gifts, and it is carved from precious natural stones, which has great collection value, such as Duan inkstone, Yi inkstone and so on. Everyone who gets a piece likes it very much. As business gifts, it is better than those electronic products, tobacco and alcohol. Nowadays, many people who pay attention to grades begin to give away such cultural products as gifts. Antique jade is too expensive, and the price of inkstone has not been speculated, so many high-end customers choose to give such products away. At the same time, self-mockery is not a bad thing. Mr. Lu Xun's self-mockery is well known. Self-mockery upstairs can be completely understood as dissatisfaction with one's own achievements and an encouragement to oneself. So in a sense, there is absolutely no problem.
