"Washing Yumen in Dai Li" does not mean that Dai Li (a famous anti-Japanese soldier in China who once served as the head of the intelligence agency) personally washed a place, but refers to an espionage operation related to War of Resistance against Japanese Aggression arranged by the intelligence agency presided over by him, codenamed "Washing Yumen".

According to relevant historical records, the "Xiyumen" took place in 1943. Its purpose was to send a group of overseas Chinese spies to invade Fujian occupied by Japan, and to weaken the Japanese forces in the southeast coastal areas of China by collecting intelligence and assassinating.

This action is called "Cleaning Yumen Pass" because Yumen Pass is an important pass on the ancient Silk Road. Dai Li believes that Fujian is the key area occupied by Japanese invaders, and it is also of great strategic significance to compare this "Yumen Wash" operation.

Second, in memory of my friends Xu Liang and Wang Kong 'an who took the exam together (later became important members of the military system), I also took Dai Li from the gentleman in the car. I got off in Dai Li, and one day I got off the bus and rode across the horse. One day I will meet you.
