Zheng Banqiao drinks.
Zheng Banqiao, a painter and calligrapher in Qing Dynasty, was a county magistrate in Weixian County, Shandong Province. One spring, he was walking in the street with a pot of wine, reciting poems and painting. He happened to meet his old friend Yoshiyama, who said, "Didn't you invite me to drink alone?" Zheng Banqiao said, "Please, I'd love to, but you're late. I'm out of wine. " Lushan asked, "How much wine did you drink alone?" Zheng Banqiao smiled and sang a poem: "I have a pot of wine to carry along the street. Double my poem and draw a picture. Write poems and draw pictures, and drink all the wine in the pot. How much wine do you think is in my pot? " Jishan blinked for a long time and said, "I calculated that there are seven or eight glasses of wine in your pot." Zheng Banqiao said, "Yes, you are very clever." Children, do you know how to calculate the mountain map?
