Liao Mengxing is the eldest daughter of Liao Zhongkai and He Xiangning, she held important leadership positions after the founding of the People's Republic of China, but she had a legendary experience before the liberation. 
Liao Mengxing said that she had served as Song Qingling's secretary for ten years, but during this period she had another important identity, and Song Qingling had no idea about it. Liu Mengxing was born in Hong Kong in 1904. She is the eldest daughter of Liao Zhongkai and He Xiangning. 
Liao Zhongkai and He Xiangning In 1902, Liao Zhongkai and He Xiangning studied in Japan, where the couple met Sun Yat-sen. Under the influence of Sun Yat-sen, they had a revolutionary consciousness and were determined to overthrow the decadent Qing Dynasty. After the establishment of China, Sun Yat-sen resigned from the post of temporary major and gave way to Yuan Shikai, but Yuan Shikai engaged in restoration, and "the second revolution broke out". Liao Zhongkai actively participated in the revolution against Yuan, was wanted by Yuan Shikai, and had to move his family east to Japan to avoid trouble. During the day, an incident happened that made Liao Mengxing and Song Qingling form an indissoluble bond. 
Sun Yat-sen and Soong Ching-lingIn 1915, Sun Yat-sen and Soong Ching-ling held a wedding in Japan, when Liao Mengxing was only eleven years old, but because he was fluent in Japanese, he acted as the interpreter for the wedding. In fact, Liao Mengxing served as Song Qingling's secretary. In 1919, Liao Zhongkai returned to China with his family. Later, Liao Zhongkai came to Guangzhou, and because Chen Jiongming staged a mutiny, Sun Yat-sen was deposed, and Liao Zhongkai was imprisoned. After Sun Yat-sen returned to power, he appointed Liao Zhongkai as the party representative of the Whampoa Military Academy, and Chiang Kai-shek as the principal. At that time, Liao Mengxing was already 20 years old, and under the guidance and influence of her father, she and her younger brother Liao Chengzhi joined the Kuomintang. But in 1925, after Sun Yat-sen's death, Liao Zhongkai was assassinated. It can be said that the ups and downs of Sun Liao's two families are closely linked, so the relationship between the two families is very deep. After the outbreak of the Anti-Japanese War in 1937, at the suggestion of ***, Soong Ching-ling went to Hong Kong to contact people from all walks of life for the Anti-Japanese War. 
Song Qingling was also at this time, Liao Chengzhi was sent to Hong Kong as the director of the Eighth Route Army Office. Liao Mengxing and Liao Chengzhi are also working hard in Hong Kong to fight for the power of justice for all parties. Because of the common goal, in this way, Liao Mengxing's sister and brother have more intersections with Song Qingling. At this time, Liao Chengzhi planned to set up a Chinese aid organization, and the leader of this organization must have prestige. They felt that Soong Ching Ling was the best candidate. In 1938, the Alliance for the Defense of China was established in Hong Kong, with Soong Ching-ling as the chairman, Soong Ziwen as the president, and Liao Mengxing as Soong Ching-ling's secretary and director of the "Baomeng" office. "Baomeng" is a national salvation group, which mainly builds a platform for the demand side and the demand side of capital and materials, and provides a bridge and link. The staff of "Baomeng" are basically part-time, and only Liao Mengxing is full-time. Therefore, she and Song Qingling have a closer connection. Liao Mengxing is the eldest daughter in the family, she is favored by He Xiangning, and she has been informal, vigorous and resolute since she was a child, so she doesn't like to dress up. Once, Song Qingling reminded her that for the sake of revolutionary work, she had to put on makeup when she went out. Liao Mengxing accepted this suggestion and later began to put on makeup. After the fall of Hong Kong, the "Baomeng" moved to Chongqing and worked in the Chongqing office of the Eighth Route Army at No. 50 Zengjiayan. Liao Mengxing continued to serve as Song Qingling's secretary under the instruction of ***, and at the same time served as the liaison between *** and Song Qingling. 
Zeng Jiayan No. 50 was the focus of the Kuomintang spy surveillance, so as soon as Liao Mengxing arrived, ** let her act publicly as "Mrs. Li" and taught her the experience of fighting wits and courage with the spies. For example, when a spy is following, don't panic or look at him, you can just go into the store and buy something as if nothing happened, and then slip through the other door. Once, Liao Mengxing was targeted by the spy when she went out on the bus to deliver secret documents, she sat casually against the door, but before the bus arrived, she took advantage of the spies' unpreparedness and jumped out of the car to leave. At that time, buses in Chongqing did not have doors. Liao Mengxing safely delivered the secret documents to Song Qingling. In 1949, Liao Mengxing had to leave Shanghai because he was blacklisted by the Kuomintang. Since then, she has ended her ten-year secretarial career by Song Qingling's side. But as of this time, Song Qingling still didn't know Liao Mengxing's true identity. It was not until 1953, with the consent of the organization, that Liao Mengxing revealed his true identity. In fact, Liao Mengxing joined the Communist Party as early as 1931. After the founding of the People's Republic of China, Liao Mengxing was transferred to the Liaison Department of the All-China Women's Federation as the director. In 1988, Liao Mengxing died at the age of 84.
