Is Liu's calligraphy a fake?

Liu's calligraphy is fake. Liu is a famous calligrapher in China, and his calligraphy is known as the "master of epigraphy". Due to the limited number of Liu's inscriptions and postscript and the large market demand, some fakes and imitations have appeared in the market. Some merchants or individuals will make and sell Liu's fakes in order to gain illegitimate interests. These fakes may be made of inferior materials and techniques, or they may be made by computer imitation technology, which cannot achieve the artistic value and historical value of the genuine products.
