Huangzhou, the "master" who painted donkeys, only felt the shape of donkeys when he started painting donkeys. Later, he squatted beside the fields and markets and observed the dynamics of donkeys thousands of times. Familiar with the various postures of donkeys, donkeys are vivid in their works. He painted thousands of donkeys, observed donkeys for decades, and waited until there were all kinds of donkeys in his chest before he got a vivid shape. He said: "What appears on the screen is a drop of water in the ocean of life, but this drop of water depends on the accumulation of life." (Quoted from Art World 1982 Lu Hua's Painting Donkeys in Huangzhou) Artists must observe, experience and feel the real life. Only when the flame of life burns can the artist's strong feelings, rich imagination and artistic creativity shine brilliantly. Art comes from social life, which is the source of art and the only source.
