The emperor is also a position, and court officials are paid, so the emperor should also have his own coffers. At that time, it was called the Ministry of Internal Affairs, where the emperor usually went in and out. Judging from the cost of Qianlong, he must have a lot of small coffers.
However, no amount of money can support Qianlong. He has been tossing around like this, so a lot of extra money came from He Shen, Qianlong's favorite courtier at that time. He Shen is a famous corrupt official, but judging from the emperor's protection for him, he must have benefited a lot. Of course, besides He Shen, he has a lot of coatings. From an early age, the emperor was a rich man, and the coating had to pay rent just like the farmer's. Besides renting land, you can also make a lot of money by doing business such as salt, silk and so on.
As for spending money, there is a saying that spending money is like running water. Any meal he has is the food for ordinary people for a month. Everyone knows that Ganlong likes going to Jiangnan. He has been to Jiangnan seven times in his life. Every time he goes to Jiangnan, it is quite ostentatious. It takes a lot of money to build palaces, find beautiful women and taste delicious food.
