The eunuch in the south of the Yangtze River put a spoonful of sugar in every dish because Emperor Qianlong couldn't eat good food at all in the palace. In order to prevent others from poisoning, it has been several hours since the food was cooked and brought to Emperor Qianlong's side. The delicious food has been lost a lot, and what Emperor Qianlong ate was only cold and unpalatable. If you eat good food in Emperor Qianlong of Yangzhou, you can't eat it in the palace, so you can only put a lot of sugar in it to prevent Emperor Qianlong from wanting to eat Yangzhou food in the future.

The emperors in ancient times were the most enjoyable emperors in the world, but in order to prevent the bad guys from having the chance to poison them in food, their diet had to go through a series of poison tests before it could be sent to them, ensuring that the food could be eaten without any problems. Although there are so many procedures, every emperor has to collect the best cooks and the best ingredients from all over the country and send them to the palace to cook food for the emperor.

The cooks and eunuchs in the palace want to eat some foods that are not common all the year round in order to prevent the emperors from calling the roll, so many seasonal vegetables and fruits will not be given to the emperors, in case they can't find them in the future, and the emperors will cut their heads off if they don't eat them. Therefore, it is the same to eat Yangzhou food. In order to prevent the Qianlong emperor from missing it in the future, he directly made the food very sweet at the root, so that the taste of the original food was lost, so that the Qianlong emperor would not feel delicious and would not say that he wanted to eat it later, and their lives would be saved.

Yangzhou cuisine can be cooked by the chef in the palace, but it will definitely not be like what he ate in Yangzhou, because the original taste of the food has been lost after the layers of poison testing procedures. When Emperor Qianlong saw that the taste was wrong, he either lost his temper, cut off the head of the chef or changed the chef, so it was the eunuch who finally got into trouble. The eunuch could find someone who could cook Yangzhou cuisine, but he could not find someone who could keep it delicious after leaving it for several hours.
