White first?

Everyone knows that Li Bai is a great poet. When does he draw? Li Bai was often down and out, and once spent the night at a peasant woman's house, having no food to eat, let alone drinking. The peasant woman persuaded: What are you worried about as a gentleman? If you don't make money by writing poems now, won't you switch to painting? Li Bai thought I couldn't draw, but he promised to comfort the peasant woman as much as possible. He asked her to buy paper. At night, he closed the door and really drew a butterfly, stamped it with Li Bai's seal and told her to take it to the market and sell it for five taels of silver. When she arrived at the market, someone rushed to buy it. When she got home, she was so happy that Li Bai painted a butterfly every night and asked her to sell it. Seeing that Li Bai's paintings sold so quickly, the peasant woman didn't see how Li Bai painted them. In the evening, when Li Bai closed the door, the peasant woman secretly looked at the door. It turned out that Li Bai just prepared a piece of paper, walked to the window with a washbasin, sat naked on the paper, got up and stamped his feet, and finished painting a butterfly. After reading it, the peasant woman thought I could draw it. I went back to my room and drew a picture according to Li Bai's painting method, but when I got to the market, Li Bai's painting was sold at once, but the peasant woman's painting was accused of being fake and no one bought a penny. The peasant woman had to take it home and ask Li Bai. Li Bai looked at it and smiled: You are true, butterflies have no heads! !
