Qianfeng, the capital of Beijing, makes a living by making "galloping horses". Changshun went to Hublot Pavilion to sell paintings, which coincided with a private visit by Gan Long and Xiao Shenyang. Deeply impressed by Qian Feng's incorruptibility as an official, Qianlong bought "Ben Ma Tu" for a large sum of money in return. Xiao Shenyang and his wife Qinlian Wu went to give Qian Feng a birthday present and gave him a jade cabbage. Qian Feng refused to accept and was laughed at by Tie Tu. During the dinner, Gan Long and A Gui came unexpectedly, and at that time, the monarch and his subjects enjoyed themselves.
