Around 1919 to 1920, he met Liu Haisu for first time in Jingjia Hill, Hangzhou.
In 1946, Mu Xin began to study Western art at the Shanghai Fine Arts Institute, under the painter Liu Haisu.
"' Liu Haisu "'(; 16 March 1896 7 August 1994 ) was a prominent twentieth-century Chinese painter and a noted art educator.
In 1918, along with fellow art teachers Liu Haisu and Wang Yachen, Mr . Wang co-founded the Tian-Ma Society to advocate the ideas of modern art.
The school shared space with the Society of Chinese Artists and they co-organised activities such as guest artist lectures by Xu Beihong and Liu Haisu which increased the school s profile.
"The World of Scholars'Rocks " concludes, logically enough, in the late 20th century with a handsome 1964 hanging scroll titled " Pine Cliff and Foggy Waterfall, " by Liu Haisu ( 1896-1994 ).
His creations are exhibited in many Chinese art museums such as the China Art Museum and the Liu HaiSu Art Museum, as well as in private collections in Europe and the United States.
Under the influence of Chinese artist and art teacher Liu Haisu ( 1896 1994 ), Liu admired, and often appropriated the styles of French-based modernist painters such as C閦anne, van Gogh and Matisse.
