Deng Enming was only 20 years old when he attended a major conference, which was already jaw-dropping, but he was not the youngest of the delegates, the youngest named Liu Renjing, who was only 19 years old at the time.

Liu Renjing has been very advanced since childhood, and likes to read progressive publications, and his favorite reading material is "New Youth" sponsored by Chen Duxiu. Later, Liu Renjing was admitted to the physics department of Peking University, joined the Socialist Youth League, and was a member of the Beijing Communist Group.
At the time of the shanghai communist group meeting, the two biggest leaders of our party at that time were Chen Duxiu and Li Dazhao, but unfortunately, these two people did not have time at that time, and Li Dazhao wanted to find two of his own students to replace him.
The first person was Li Dazhao's proud protégé Zhang Guotao, who was the chairman of the Beijing Federation of Students at the time, and his status was already unusual, so it was very appropriate for him to go.
The second person was supposed to be Deng Zhongxia, the second brother of the Beijing Communist Group, but Deng Zhongxia did not have time, and he was going to attend a meeting of the Young Chinese Society. Next, it was the turn of the third master brother Luo Zhanglong. Luo Zhanglong was a well-known worker leader, but he was organizing a workers' strike at the time, so he didn't have time. Li Dazhao asked several students in a row, but everyone had no time, and finally Li Dazhao found the youngest Liu Renjing.
Liu Renjing was young and vigorous at the time, and she was very enthusiastic about this kind of thing, so she immediately agreed.
With such an experience, it is reasonable to say that Liu Renjing's future in our party will be very bright, but in the second year he embarked on another path. Because Liu Renjing was proficient in many languages, Chen Duxiu took Liu Renjing by name to the Communist International Conference in the Soviet Union and let him serve as his interpreter. Liu Renjing was originally a super fan of Chen Duxiu, so she agreed without hesitation.
In the Soviet Union, Liu Renjing became acquainted with Trotsky, who, although also an important figure in the Soviet Union, was Stalin's sworn enemy. Liu Renjing admired Trotsky very much, and even after Trotsky was expelled by the Soviet Union, he made a special trip to Turkey to visit Trotsky, and stayed for more than a month.
As a result, after returning to China, Liu Renjing regarded herself as "Trotsky's spokesperson" and went farther and farther away from domestic communism. This also doomed Liu Renjing's subsequent experience to be very bumpy, he not only broke away from the organization, but also defected to the Kuomintang, but he was always not welcomed by anyone. It was not until 1949 that he decided to change his past and return to Beijing.
The organization was still very tolerant of him, arranging for him to teach at Beijing Normal University and also serving as an interpreter for the People's Publishing House. In the end, Liu Renjing died unexpectedly in a car accident at the age of 85, but he was also the last representative to die.
