Short story about philosophy:

1. Xu Beihong invited Qi Baishi.

It's my duty to take care of the thatched cottage, not to mention the old painter who carved insects. The sea is clear and the moon is full, and the cane helps the dream to visit Xu Xi. This is the poem of "Looking for the Home under the Moon" presented by Qi Baishi to Xu Beihong, and I sincerely appreciate Xu Beihong's kindness of "looking after the grass in the cottage".

2. I have long admired his name.

in the autumn of 1929, Xu Beihong, a modern painter and art educator, became the president of Beijing Institute of Art.. Convinced that only excellent teachers can cultivate excellent students, he carefully selected professors, and the first person he intended to hire was Qi Baishi.

Qi Baishi, a teenager, studied painting. After half a century of hard work and unremitting efforts, he finally became one of the masters of painting. He settled in Beijing in 192 and specialized in selling paintings and engraving. Xu Beihong has always admired his character painting skills and called him a true master of art.
