Nineteen years of Qing Daoguang. Lin Zexu was appointed as an imperial envoy and banned smoking in Guangzhou. Britain, the United States, Russia, Germany and other countries in Guangzhou used western food to entertain Lin Zexu, and served an ice cream after dinner. Because Lin Zexu didn't know why ice cream was delicious, he thought it was hot when he saw it, and let the food cool before eating. Lin Zexu was so angry that he blew his beard and stared. However, Lin Zexu is also very quiet. After a long time, Lin Zexu gave a banquet to entertain the leaders. The dishes he invited to eat were all cold dishes, and then he served a taro paste, which was gray in color and shiny on the surface. It doesn't look like traces of hot air. Those leaders thought it was also a cold dish, so they scooped it up with a spoon and sent it to their mouths. Ha ha! When cheated, the leaders are screaming at the top of their lungs. Lin Zexu laughed internally and kept apologizing, saying that they didn't know that this "taro paste" was cold outside and hot inside.
