After the Japanese invaded China in an all-round way, there were quite a few traitors in China, some of whom became traitors because they were afraid of death, some of whom became traitors for the sake of getting rich, some of whom were traitors for the sake of being officials, and who had their own intentions when they were traitors, but there was one big traitor who was different, and he regarded being a traitor as a kind of pleasure.

This person is Liu Yutian, known as the "first traitor in southern Liaoning", in 1870, Liu Yutian was born in Dalian, Liaoning Province, a large landlord family, from childhood to live a life of fine clothes and food, do not need to worry about food and clothing, received a good education.
As a reader, Liu Yutian is keen on the imperial examination, but he has repeatedly failed, and only blames him for his limited ability, even if the imperial examination falls on the list, it does not affect his life, after all, he has a rich family property, a lifetime of food and clothing, so why should he be a traitor?
Some people say that he is careless in making friends, and some people say that he is to take revenge on the late Qing Dynasty, in short, he is not a high-ranking official for money, nor is he forced, and he regards being a traitor as a pleasure and an achievement, which is really incomprehensible.
During his studies, Liu Yutian made a friend named Zheng Yongchang, the two talked very speculatively, and soon became friends with Mo Rebellion, and later Liu Yutian learned that this Zheng Yongchang was actually a Japanese spy, lurking in China for many years, and had provided a lot of intelligence for the Sino-Japanese Naval Battle.
It was under the guidance of Zheng Yongchang that Liu Yutian embarked on the road of traitors, and on October 24, 1894, the Japanese army landed at the mouth of the Garden of the Zhuanghe River in Dalian, and Liu Yutian, then 24 years old, willingly gave the Japanese Kou a guide, officially embarked on the road of traitors, and went farther and farther.
A few days later, on November 6, the Japanese Kou captured the city of Jinzhou in Dalian, Liu Yutian did not hesitate to work hard to drive a carriage with more than 10 truckloads of supplies to comfort the Japanese army, the traitorous behavior was nakedly revealed, and after the defeat of jiawu, the late Qing Dynasty issued a warrant for Liu Yutian's arrest.
Liu Yutian as a traitor can be described as a dead heart, in the face of the late Qing Dynasty wanted, he simply fled to Japan, and changed a Japanese name for himself called Kameyama Matsutaro, which is a complete betrayal of his ancestors, after arriving in Japan, he entered the Japanese Zenlin Academy to teach Chinese.
In 1898, Liu Yutian became a professor of Chinese at the Japanese Army University and successfully admitted Japanese nationality, with the development of Japanese industrialization, Liu Yutian more firmly followed the Japanese master, and even regarded Japan as his hometown, and also married a Japanese wife.
After the outbreak of the Anti-Japanese War, Liu Yutian played a role again, he returned to China, drew a detailed map of the village road for the Japanese army, provided intelligence for the Japanese invasion, this time Liu Yutian even sold the rented house and field, and the money obtained bought two fighter planes.
He donated fighters to the Japanese army as a weapon for bombing Chinese, and it is not known how many Chinese died under the bombers he donated, and when Japan was defeated, Liu Yutian took refuge in Japan again, this time the Japanese did not take him in because he was worthless.
After that, Liu Yutian lived in hiding in Tibet, hiding in Dalian, Shenyang, Jilin and other places, and was not found out until 1951, when Liu Yutian was 81 years old, and this traitor was still sentenced to death, ending his criminal life.
