Calligraphy is the accumulation of ancient people's experience. As the saying goes, it is just one of them. In the history of China, how many people copied and studied the calligrapher Wang Xizhi all their lives, but who surpassed Wang Xizhi? However, this famous calligrapher won a place in the history of calligraphy in China only because he has studied this calligrapher all his life. If he had done something unconventional from the beginning and wanted to create it himself, there would have been no such person.
So there is nothing wrong with learning calligraphy from the ancients seriously.
