"The Xiongnu are not broken, why should the family be returned" This is the famous saying of Huo Huo, a great general during the Han Dynasty in China, indicating that foreign enemies have not been completely eliminated, where is there still a home? At the same time, it also expresses the lofty aspirations of our people to fight against foreign enemies.
In modern times, our country has been constantly subjected to foreign invasions, during which time many unsung heroes have sacrificed on the road of struggle against the enemy, and during the civil war, many underground personnel of our army have gone deep behind enemy lines and made great sacrifices.

These outstanding fighters are all talents who are one of the best in the world, but they all struggle on the front line with their enthusiasm and love for the motherland. Many of them fell on the eve of dawn.
Of course, there are also some underground workers who have moved behind enemy lines who have returned safely, and the three we want to talk about today are Shen Anna, Guo Rugui, and Duan Boyu.
Shen Anna was a woman with a very superior birth environment, in that era it can be said that she was rich and rich, and she was also very beautiful in her own life, and in that era she was both rich and beautiful.
When she was a child, Shen Anna's dream was to become an actress, and becoming a household star was of course the dream of every young girl, but unfortunately, she was born in that era, that era of war.
War has torn a country apart, and it has also torn apart thousands of families in this country, and all people with lofty ideals hope to save this country through their own efforts.
Shen Anna is such a person.
By chance, she came into contact with the red revolutionary ideal, so she threw herself into the revolution without hesitation. Since then, a rich family has disappeared, and some are just proletarians whose hearts are full of noble ideals.
Because of her good looks and her family's very good conditions, she became an agent lurking behind enemy lines, responsible for collecting intelligence on the Kuomintang army. As an intelligence officer, you have to go through countless tests to survive from a complex environment.
After the founding of the People's Republic of China, Shen Anna entered the National Security Bureau, also engaged in her own work, because of her special status, so her deeds must also be kept secret for a long time, until decades later, her deeds, not known.
In her later years, this long career as a secret agent still brought serious psychological trauma to Shen Anna, and sometimes recalled the years when she was once frightened and feared, and this kind of self-sacrificing unsung hero was really touching.
Guo Rujie was very famous during that period, and his fame was that he also held important positions within the Kuomintang, and even became a lieutenant general in the Nationalist army at the height of his official position, which can be said to be the biggest spy in the official position.
Similarly, Guo Rujie was actually born in a scholarly family, and he was also well educated when he was young, and he was also one of the first progressive young people to come into contact with new cultural ideas at that time, and after accepting these progressive ideas, he also began to enter the road of salvation and survival.
Moreover, in the midst of this continuous revolution, he himself brought out a team and achieved the position of division commander, but we all know that in that era of melee, many great warlords disappeared in each other's conquests, and there was no good end.
So as a person with advanced thinking, he is also thinking about joining a team that can save the country more effectively.
Eventually he was conquered by the advanced ideas of communist thought and joined the ranks of our Party. And because he was also a warlord before, after joining our party, he chose to return to Sichuan to continue to lead the team.
After returning to Sichuan, he found that his cousin had joined the Kuomintang camp. At that time, the Kuomintang was going around clearing and suppressing our Party. Therefore, in desperation, he went to Japan to study, and then lost contact with the organization for various reasons.
Later, at the beginning of the War of Resistance Against Japanese Aggression, he resolutely returned to China while studying in Japan, and was admitted to the Kuomintang Army University to study military knowledge, and because of his excellent results, he soon served as the chief of staff in the army.
Slowly, Guo Rujie became Chiang Kai-shek's confidant and participated in many battles. However, just as the so-called Cao Ying's heart is in Han, no matter how generous he is in the Kuomintang army, he still has his heart set on our party.
It is precisely because he is at the top of the Kuomintang that he sees that the internal factions of the Kuomintang are intricate and complex, and they are in the midst of corruption, and such a party cannot save China. Later, in various ways, he finally contacted people in our party and began to spy.
Although he made outstanding contributions in the War of Liberation and was deeply influenced by Marxism, due to his identity problems, he never formally joined the Party, and only after the founding of New China did he successfully join the Party under the recommendation of New China and become a member of our Party.
However, it is regrettable that after Guo Rujie joined the party, he did not really start to serve the people, and he died one step ahead of the car accident, which is indeed regrettable.
Duan Boyu also made important contributions in the undercover process, because he also penetrated into the top level of the Kuomintang, the Military Affairs Office of the Presidential Office.
He followed Zhou Enlai very early on and began to participate in various patriotic salvation movements, so he also came into contact with the red ideology of our party relatively early, and soon joined the party with honor, and during the War of Resistance Against Japanese Aggression, he himself opened a newspaper in Shanxi to spread advanced ideas to the people.
Later, after Taiyuan was attacked by the Japanese army, he lost contact with our party and joined the Kuomintang army in desperation.
After the internal stabilization of the Kuomintang, he contacted some underground party members of our party through some channels, and joined the party for the second time, officially starting the task of red spies.
Because Duan Boyu was engaged in newspaper work before, he had a strong writing background, and Duan Boyu began to participate in various activities to save the survival of the people very early, so his ability was quickly recognized by the top level of the Kuomintang, and successfully entered the Military Affairs Bureau of the Kuomintang's Presidential Office.
And it is precisely because of his presence that our Party has obtained his intelligence in many battles in the War of Liberation and thus won crucial victories.
After liberation, he continued to contribute to the cause of China's construction and was engaged in the secretary of the party committee of the Institute of The Chinese Academy of Sciences, so with such outstanding talents, our party's liberation cause can be carried out in an orderly manner.
