China has a long history of 5,000 years. Ancient Chinese literati attached great importance to "literary play", but it was not called literary play in ancient times. The ancients played the literary drama Four Treasures of the Study. The literary play we are talking about now actually comes from Four Treasures of the Study. Although Four Treasures of the Study was founded very early, it developed into the Tang and Song Dynasties, that is, the traditional art of calligraphy and painting tended to be mature and perfect, and after the formation of the literati group, it really found and realized its due position and value, and became an indispensable tool for scholars and even emperors to study desks.
