Introduction to Tang Yin's Department of Boating: When Tang Yin saw the beautiful mountains and rivers of Shanghu Lake in Yushan, he immediately became interested in painting. He specially took a small boat to admire it and splash ink. Every time Tang Yin finished painting, he always felt that it looked similar but not similar, so he painted again. He painted one picture; he still felt that Yushan was not realistic enough, so he painted dozens of pictures, but they were all rolled into paper balls and thrown into the cabin. In the evening, the boat circled Yushan and returned to the city. After paying the money, Tang Yin abandoned the boat and wanted to leave. , the captain asked, "Do you want the painting in the cabin?" Tang Yin said, "This is a fire starter in the stove, it can be burned." After Tang Yin left the boat, the owner of the ship hurriedly took out several paper balls from the cabin, spread them out and smoothed them out to look at them. Each of them was of fine quality. After counting, there were seventy-one pieces in total. The next day, the owner of the ship took them to the market to sell them, and they were quickly sold. People snapped them up and made a fortune. In order to commemorate this allusion, later generations set up the "Tang Yin tie boat" here.
