What is the purpose of painting collection in Wanmu Caotang?

Zheng Wanmu Caotang Tibetan Painting Catalogue is not only a treasure of Kang Youwei's calligraphy art, but also a theoretical work of Kang Youwei in painting. Kang Youwei has been a pervert since he was a child. 1889, when he wrote to the Qing emperor for the first time, he was attacked by feudal diehards. He replied: "Wash your heart and hide secrets, but sweep away your mind" (Preface to Guang Yi Shuang Zhou) and "Read the tablet every day to see the thousands of kinds of stones collected by collectors in the capital" (Chronicle by Kang Nanhai). He is also good at calligraphy. He used a special pen when he was in the swimming pool, and he was arrogant and rude. He was a calligrapher who was as famous as Wu Changshuo and Shen in the late Qing Dynasty.
