/kloc-in the 0/8th century, an Austrian doctor was treating a patient before he was diagnosed, and the patient died suddenly.

Five easy-to-draw white stone old people
Qi Baishi, a carpenter, became a painter by himself and won the World Peace Prize.

His paintings after 60 are obviously different from those before 60. After 70 years old, his painting style changed again. After 80s, his painting style changed again. It is said that Qi Baishi had five relaxed painting styles in his life. It is precisely because the old man Baishi is still non-stop after his success that his works in his later years are more mature than his early works, forming a unique genre and style.
