It is best to buy it on Taobao, a few hundred dollars at a time, just ordinary Qingtian and Bahrain; Beginners buy a stone from 200 yuan. What kind of teacher are you? Beginners of seal cutting will inevitably break, and if they break, they will have to be worn off and engraved again. The printing practice of 200 is too extravagant. I will buy 200 pieces of stone at a time, dozens of pieces, enough for me to use for several months. It is a better choice to buy a better knife in the future, or to finish carving before collecting it, so it is not recommended for novices to buy too expensive stones, which is not only an economic problem.
