Introduction to the banquet hall: The banquet hall is a place where Puyi specially gives banquets. Whenever the Wanshou Festival or celebration day, Puyi holds banquets here for officials and guests. The room was arranged in a "concave" shape, with Puyi sitting on the throne in the middle. The ministers were seated one at a time according to their positions. They all ate the same food, but Puyi was suspicious by nature and was afraid that the Japanese would be in his meals. After poisoning, every time the meal is cooked, the chef tastes it, and the guard tastes it, then puts it in a special thermal box, seals it, and opens it in front of him, so that he can eat with confidence.
