Unofficial history counted several famous thieves in the Republic of China, including Li Yunlong.

In people's impression, the so-called "informer" is born to fly high and fly high. They are thieves with special skills. Although not all of them are chivalrous, they must have certain singing skills and have the potential to become legends. Snitch is actually an ancient industry, which has been mentioned in many romantic novels before.

During the Republic of China, the whole society was in chaos, and "informers" became radical figures. With superb skills, they climbed over the eaves, entered the house, followed anything of value, and some even became killers hired by others to do shady things.

"Swallow Li San" was the most famous informer in the Republic of China. However, in folklore, there is more than one person who holds this title. After all, this title is very easy to use and has a wide popularity. It is a well-known IP and has not applied for a patent. So it has become synonymous with many informers.

The earliest version that can be verified is Yan Zi Li San in Cangzhou, Hebei Province. This "Little Swallow Li San", formerly known as Li Yunlong, is also called "Little Dragon". He is from xian county, Cangzhou, and the third in his family. He was born around 1837, and his descendants still live there.

Li Yunlong is mainly active in Beijing-Tianjin-Hebei and Northeast China. It was the first to use the nickname "Swallow". It was called "Swallow" because his surname Li ranked third. He is a thief, robbing the rich and helping the poor, so he has a good reputation among the people. After Li Yunlong, there was another "Swallow Li San", known as "Old Swallow Li San".

"Old Swallow Li San", whose real name is Li Jinghua or Li Hong, was born around 1898. He was originally from Zhuozhou, Baoding, Hebei Province, and came to Cangzhou with his uncle in his early years. In Cangzhou, a place famous for martial arts, he learned some martial arts, especially Qigong.

Later, he started a business and had no capital. Li Jinghua once committed crimes in Hubei, Henan and Anhui, and even went to the home of Luoyang police commander at that time.

When Li Jinghua commits a crime, he often chooses a rich family. After committing the crime, a swallow folded with white paper will be left, or the name of "Swallow Li San" will be written down, and the name of "Swallow Li San" will begin. Because he took out stolen things from time to time to help the poor, he was also regarded as a "grand theft auto" by the people, and thus gained a good reputation.

Of course, Li Jinghua sometimes failed, and eventually he was arrested by the police and imprisoned. Finally died in the detention center. The first two "Yanzi" are just right, and the next "Yanzi Li from Shandong" is somewhat "running away".

"Shandong Li Yanzi", formerly known as Li Shengwu and alias Li Huatian, was born in Yucheng, Shandong. He used to be a Taoist in Tiantai Temple in Jinan, and later learned a lot from an old Taoist in Wutai Mountain. From 1936, Li Shengwu committed crimes in Jinan and soon became famous.

Li Shengwu is a professional informer. He steals from almost everyone. He did not let go of the home of Han Fuju, then chairman of Shandong Province. During the War of Resistance against Japanese Aggression period, he dared to steal from the Japanese Gendarmerie Command, and even failed to enter the people's government office several times.

After the founding of the People's Republic of China, there was no living space. He was captured by the police and executed in 1949. Li Shengwu himself has a bad style and is bold. He committed many murders and it was reasonable to be shot.

Duan Yunpeng was born in 1904 in Jixian County, Hebei Province. He swallowed Li San from Li Jinghua and learned all his skills. Duan Yunpeng is famous for being the home of Okamura Ningji, the commander of the Japanese invaders, and stole many precious treasures. Although the Japanese special high school and the Peiping police station jointly dispatched, they failed to capture him.

Later, Duan Yunpeng was absorbed by the Kuomintang military system and became a military spy, specializing in various espionage activities. Since then, Duan Yunpeng was sent by the military system to assassinate revolutionaries and did many bad things. 1950, Duan Yunpeng was finally captured by the police and imprisoned. 1969, Duan Yunpeng was executed.

Wang Jinquan was also a famous thief at that time. His main story is stealing from Dai Li's house in 1940s, which has gained a lot. Although Dai Li is sad about his property, he appreciates Wang Jinquan's skills. After catching Wang Jinquan, he wanted Wang Jinquan to join the military organization.

Wang Jinquan was not interested in these things, but slipped away during the escort. Since then, there has been a lot less information about him. Wang Jinquan is also a rogue, without any stain, and he is a bold man, so he is also praised by people.
