During the revolutionary period, there were many heroes who sacrificed their lives for the country and died on the battlefield, but there were also many traitors in that period, who left their homes and betrayed the people for their own selfish desires. At that time, there was a member of our party named Gu Shunzhang, who later surrendered to the enemy and defected, and Gu Shunzhang's defection caused very great losses to the revolution. Gu Shunzhang later worked for the Kuomintang, but because his use value was almost gone, he was executed by Chiang Kai-shek. There are many traitors in history who most of them did not end well, and Gu Shunzhang betrayed the Communist Party for his own selfish desires and was finally punished. Cai Mengjian, who captured the Communist traitor Gu Shunzhang, kept Wuhan University and Wuhan No. 1 Yarn Factory during the Anti-Japanese War, and later helped Zhang Guotao, after Zhang Guotao's death, Cai Mengjian helped Zhang Guotao's family take care of Zhang Guotao's funeral. Cai Mengjian almost changed history twice, he was a long-lived man, living 96 years old. 
Kuomintang member Cai Mengjian. Cai Mengjian was born in 1905 in a small village in Luxi County, Pingxiang City, Jiangxi Province. When Cai Mengjian was in middle school, he secretly participated in the underground organization of the National Revolution led by Dr. Sun Yat-sen. Later, Cai Mengjian studied economics at Qingdao University, and after graduation, he went to Japan to study. During the Anti-Japanese War, Cai Mengjian actively participated in the Anti-Japanese War. In 1938, he participated in the very famous Battle of Wuhan, an important transportation hub in China, and after the fall of Nanjing, Wuhan once became the temporary capital of the people. At that time, Cai Mengjian served as the deputy commander of the Wuhan garrison, mainly responsible for the defense of Wuchang and Hanyang. After the all-out war of resistance, Chiang Kai-shek once issued a call for the "scorched earth war of resistance", for this call, the army has two understandings: one is to destroy all production and living equipment, so that the Japanese army can get a piece of scorched earth;The second is to fight the Japanese army to the end, even if the Japanese army burns our country to a scorched earth, we still have to fight to the end. Cai Mengjian once had a conflict with his boss because of the understanding of this call. 
In the battle to save Wuhan No. 1 Yarn Factory and Wuhan University, because the Japanese army's combat ability and equipment were stronger than China's, the Japanese army later bombed Wuhan, and the national army was very large, and finally had to withdraw from Wuhan. The day before he withdrew from Wuhan, Cai Mengjian received an order from his superiors that Cai Mengjian organized the bombing of the newly built Wuhan University and the Wuhan No. 1 Yarn Factory founded by Zhang Zhidong at the end of the Qing Dynasty. After Cai Mengjian received Luo Zhuoying's letter of order, he thought that it was not wise to bomb the school and the factory, and the state had invested a lot of money in Wuhan University, which was a place to cultivate outstanding talents for the country. 
The Wuhan No. 1 Yarn Factory is a very valuable asset of China's modern industrial accumulation over a long period of time, and the Wuhan No. 1 Yarn Factory is still an enterprise that produces the daily necessities of the people, and the yarn mill and the university are not military base facilities, and it is not beneficial to blow them up. Not only that, but blowing them up will also damage our national strength to a certain extent, which will affect the lives of the people, and it will cost a lot of manpower and material resources to build them later. Not only will it not do any good against Japan, but it will also destroy the material conditions for resisting the enemy. Cai Mengjian has always dared to think and do, "The generals are outside, and the military orders are not subject to it." This time, Cai Mengjian recklessly and the orders of his superiors asked his subordinates to cancel the operation of bombing the school and the factory. He was willing to pay the corresponding price for his actions, and later his superiors accepted Cai Mengjian's action to cancel the bombing of the school and the factory, and at Cai Mengjian's insistence, Wuhan University and the First Yarn Factory were saved. 
During the Battle of Changsha shortly after, the Changsha army set fire to some important buildings and residential areas without waiting for the enemy to enter the city, which later caused the displacement of the people of Changsha City and their homelessness. The people of Changsha City complained, many people went to the province and Chongqing, and the people of Changsha City were panicked for a while, and in order to stabilize the people's hearts and the army's hearts, Chiang Kai-shek had no choice but to remove the chairman of Hunan Province, and also shot the commander of the Changsha garrison and the two chief officers. Later, the turmoil was calmed down, and the facts proved that Cai Mengjian's previous decision was very correct. 
In 1941, Lanzhou was established as a city, and Cai Mengjian served as the first mayor of Lanzhou. At this time, Lanzhou's economic foundation and infrastructure development were relatively backward, and Lanzhou was very seriously destroyed during the Anti-Japanese War. As the saying goes, "if you want to get rich, you must first build roads", Cai Mengjian widened roads, improved traffic conditions, and engaged in greening. Some of Cai Mengjian's practices have harmed the interests of some capitalists, and they have made a lot of stumbling blocks for Cai Mengjian behind his back. Regardless of these pressures, Cai Mengjian insisted on continuing to promote the construction and development of Lanzhou's city. When widening the road, most of the houses along the road were under the control of the chairman of Qinghai Province and the chairman of Ningxia Province, and Cai Mengjian personally went to seek the consent of the two provincial chairmen, and proposed to the chairman of Ningxia Province to name the road after his father. Later, after the successful completion of the road, when Chiang Kai-shek came to inspect, he admired Cai Mengjian's approach very much, and later built Lanzhou into a model city after the war. 
Twice almost rewrote history In 1931, the people of Hankou came to a magic troupe, and the chief magician Hua Guangqi was about twenty-seven or eighteen years old, a little fat. His performance skills are very superb and he has won the love of many people. In fact, this chief magician is a **, he eliminated many traitors and killed a lot of Kuomintang spies, he is very talented and witty, so the party sent him to escort Zhang Guotao and Chen Changhao. After completing the task, Gu Shunzhang violated discipline and wanted to make some money, so he stayed in Hankou and disguised himself as a magician. The traitor You Chongxin recognized Gu Shunzhang and reported it to Cai Mengjian, who knew that Gu Shunzhang was a very important figure in the Communist Party, so he quickly ordered Gu Shunzhang's arrest. 
Gu Shunzhang, who was arrested, was very calm and offered to see Chiang Kai-shek. After some consideration, Cai Mengjian decided to send a telegram to Chiang Kai-shek first, but he didn't know that "one mistake will lead to eternal hatred". Later, because the undercover agents of the Communist Party in Wuhan intercepted the telegram in advance and sent the contents to the underground contact address in Nanjing, the Nanjing Communist Party members deciphered the top-secret telegram and took countermeasures, which saved the day. **I have recalled many times that if it weren't for the "Three Heroes of Longtan", they would have been gone a long time ago. Later, *** personally ordered Gu Shunzhang to be wanted. In 1934, Chiang Kai-shek thought that Gu Shunzhang was no longer useful, so he ordered Gu Shunzhang to be executed. If Cai Mengjian did not send a telegram to his superiors at that time, but directly sent Gu Shunzhang secretly to Nanjing, he would not have been discovered by the undercover agents of the Communist Party around his superiors. At this time, there is a good chance that China's history will be rewritten. 
At the beginning of the founding of New China, Chiang Kai-shek wanted Okamura to do things for himself, and trained some officers. Cai Mengjian was the intermediary between Chiang Kai-shek and Okamura Ninji, and he secretly traveled to Japan. Later, after this incident was **, the masses of the people strongly opposed it, and the ** at this time was very unfavorable to Chiang Kai-shek. Chiang Kai-shek put the matter on Cai Mengjian, who had to flee to the United States. If Tsai Mengjian and Chiang Kai-shek's plan had succeeded, much of China's history could have been changed. In 1948, Zhang Guotao and his wife defected to their son in Canada, and in 1976, when Zhang Guotao suffered a stroke, Zhang Guotao's wife asked Cai Mengjian to discuss how to tide over the difficulties. Later, after Zhang Guotao's death, Cai Mengjian told Chiang Ching-kuo that a few days later, Taiwan remitted $3,500 to Cai Mengjian and asked him to deal with Zhang Guotao's funeral. 
Summary: Cai Mengjian almost changed history, but it failed due to various coincidences. Cai Mengjian later settled in the United States, where he died in 2001 at the age of 96. From Cai Mengjian's deeds, we can see that Cai Mengjian is an officer with excellent military talents, he can sympathize with the suffering of the people, and has his own judgment standards, dare to think and do, have the courage to bear the consequences of what he does, is very witty and flexible, and is good at flexibility. In the long course of history, there are many great heroes, but some of the characters we think are "inconspicuous", they are flesh and blood people, and they have left their own traces in history. Therefore, we should have a pair of eyes that are good at discovering the good qualities of historical figures. Characters like this, even when covered by the waves of history, still shine in the corners.
