Wang Xizhi's calligraphy art is an admirable peak in China's legal history ... What method is very rigorous?

Wang Xizhi's calligraphy art is an admirable peak in China's calligraphy history. At the age of seven, he began to learn calligraphy. With superhuman talent and diligence, coupled with the appropriate social environment at that time, he successively studied under Mrs. Wei and Uncle Wang of a calligraphy family. Later, the exquisite works of Chun Gumao, the master of seal script in Qin and Han Dynasties, were exhibited. They studied the body, imitated the hand and learned from others in one furnace, creating world-class calligraphy and being praised as "the sage of books" by later generations. Please adopt it.
