Review
Before dawn, it is often the darkest. On the eve of the liberation of all of China, the reactionaries of the Nationalist government were still fighting the beasts. The reason why the Communist army can fight the enemy indomitably is that in addition to the charge and assembly of soldiers on the frontal battlefield, it is also inseparable from the obscure intelligence dedication of underground party members.
Fu Zuoyi was a senior military official of the Nationalist government and had been operating within the Nationalist government for many years, so why did he choose to defect to the Nationalist Government in the first place when Tianjin was "lost"? High degree of political awareness? "Gentlemen do not stand under the dangerous wall" a review of the situation?

The joke of Tianjin's "defense war"
In the face of the general offensive launched by the People's Liberation Army to win the final victory, Fu Zuoyi, a general of the Nationalist government stationed in Beijing, seemed to lack a vigilance and a sense of jealousy, but his attitude of disregarding the facts and dismissing it made him lose completely.
He once proudly believed that the deployment of every inch of Tianjin's land, under the meticulous equipment of the Nationalist Government, would never allow the red bandits to take advantage of the opportunity, and once threatened that he would not need to personally dispatch a soldier and a pawn to hold out for at least three months. But the reality in front of you is another look.
At 3 p.m. on January 15, 1949, Chen Changjie, commander of the Tianjin Garrison, was captured alive and reduced to a prisoner of our party, and it took only 29 hours of effort for Tianjin to usher in liberation. Fu Zuoyi suddenly realized that he had seriously underestimated the will and strength of the People's Liberation Army.
Intelligence is a clever trick
Why can the People's Liberation Army make a quick decision? It was not until 1959 that an article published in the People's Daily revealed the mystery hidden in it, and the person who disclosed it was Liu Yalou, who was in charge of the general attack on Tianjin.
Incredible 29 hours! Just as the so-called "knowing oneself and knowing the other can never be defeated in a hundred battles," our army effortlessly formulated a targeted plan and deployment based on the layout map of the National Government's military defense secretly delivered by underground party members, and in one fell swoop defeated the Nationalist government army entrenched in Tianjin.
Fearing the power of the People's Liberation Army, Fu Zuoyi, who had become a lost dog and was unable to return to heaven, had to obediently obey the dispatches of the Communists and no longer do any meaningless struggle, at least he could abandon the dark in time.
Thus, under his example of surrender, Beijing was peacefully liberated, and the two armies stopped continuing to fight each other, avoiding all possible bloodshed and sacrifice.
The National Government is stubbornly resisting
The relationship between Chen Changjie, the commander of the Tianjin Garrison, and Fu Zuoyi was not ordinary. Fu Zuoyi fully trusted the general Chen Changjie and specially sent him to take charge of the military defense of Tianjin.
In the eyes of the National Government, Tianjin can be called a "treasure land of feng shui", an indestructible and indestructible sentry post, where the arrangement is almost 360 degrees without dead angles, there are moats and pillboxes, there is the blessing of industrial city defense, and even the power grid is erected and mines are laid!
But the blind optimism of the National Government is often easily carried away, with unimaginable results. In fact, our army has placed eyeliner within the National Government and buried its head in the enemy's work as a lurker for many years.
The perfect fit of the organizers
In 1947, when Du Jianshi, a member of the Nationalist government, was repairing the fortifications left behind by the Japanese army, Mai Xuankun was responsible for the on-site supervision of the eighth section of the project.
In order to secretly deliver urgent military intelligence to our party, he used the self-study of engineering drawings as an excuse to try his best to break through many dangers and obstacles, make accurate measurements of bunkers one by one, and clearly and unmistakably mark the most real and accurate data on the materials.
After unremitting efforts, Mai Xuankun produced a more detailed map, including the geographical overview of Tianjin and the defense of fortifications.
Then, he handed over the baton of passing on information to Wang Wenyuan, the head of the tianjin underground party at that time. Out of consideration for the confidentiality and urgency of this information, the other party did not hesitate to transfer the information to Kang Junshan, an experienced underground traffic officer.
Kang Junshan's cover identity in Tianjin is the owner of a photo studio. With his skills and skills, he knows how to handle similar levels of intelligence.
The original drawing was cut into four copies, and after the miniature shooting process, under the direct action of the special potion, all the data and graphics on the surface of the surface were all gone, appearing to be no different from daily paper, and then pasted on the photos of the two elderly people.
How to avoid the eyes and ears of the National Government along the way is the most risky test for those who bear this task. The position of the traffic officer belongs to the grass-roots level in the underground work, but it plays an irreplaceable role in carrying on the upper and lower levels.
Five big three rough simple errands, can only be equipped to pull foreign cars. Traffic officers need to have a wise mind, and the most important thing for people is to be alert.
Although Comrade Zhao Yan had not been working underground for a short time, he volunteered to take the baton for delivering intelligence. To be a qualified traffic officer, it is far from enough to rely on enthusiasm and spirit, otherwise, it is difficult to cope with the complicated situation.
Therefore, he was entrusted with a heavy responsibility with a flexible mind. On the way, he happened to encounter a robbery gang, but he cleverly got rid of it in an instant. It is simply a thrill to say, but fortunately, the "posthumous photos" finally arrived safely in the liberated areas.
There was also another comrade Zhang Kecheng, who was lurking in the Public Works Bureau of the National Government, who also got a key layout map in his hand, and after the close cooperation of the underground work, it was finally solemnly delivered to Liu Yalou's hands.
Liu Yalou witnessed this thrilling history, and it was precisely because of the existence of such a group of underground lurking workers that intelligence from the Nationalist government was continuously imported into our party.
epilogue
The workers on the hidden front are unsung heroes, who never care about fame and fortune and gain or loss, who have been squatting in the enemy's camp for many years, collecting countless valuable intelligence for our Party in a special way of working, and becoming a sharp knife planted in the heart of the enemy.
Every time they go on a secret mission, they may even reveal their identities and even pay the price of their lives! Remember their names! salute!
