Idiom story:

Wen Heke (Wen Tong) is famous for their bamboo paintings. Many people come to paint every day. Wen Neng grows all kinds of bamboo in front of and behind his house. No matter spring, summer, autumn and winter, rain or shine, he often goes to the bamboo forest to observe the growth and change of bamboo, figure out the length and thickness of bamboo branches, the shape and color of leaves, and return to his study with new insights and draw his own impressions on paper.

Various images of bamboo are deeply imprinted in his mind. Therefore, every time he draws bamboo, it seems very calm, and the bamboo he draws is vivid and lifelike. When people praised his paintings, he always said modestly, "I just painted the mature bamboo in my heart."
