Before the establishment of the resistance organization, Zeng Che had become sworn friends with some people because of Jin Lan's kindness. There are ten people in the alliance, some are military elements, and some are activists of the "12.29" movement. Eldest brother, second brother Zeng Che, third brother, fifth brother Li, sixth brother Shen, eighth brother Zhang Siming, second brother Zhao, and tenth brother Chen. I can't remember the names of others. On the basis of Tianjin Concession, the Communist Youth League developed its own organization among students in various schools. In the early days of the establishment of the League, the organization was extremely strict and the number of participants was small. Most of the participants are students with excellent academic performance in various schools, with ardent patriotic enthusiasm and firm attitude towards the enemy. Some of them were later arrested by the enemy, tortured and died peacefully without betraying their associates.

At that time, the anti-regiment elements in Tianjin schools were:

Middle schools: Sun (female), Chen (female), Feng (female), Xia Zhide (female), Zhang (female), Li Dazhan, Shen Xingan, Pan Mou, etc.

Sino-Japanese middle schools:, Wang,, Zhao, (Sun Ruoyu's original name is Sun, alias) and so on.

In addition, there are some unknown schools: Yuan, Yuan Hanqin, Zhang, Hua Daoyong (female), Hua Daoben (East China Japan Institute), Fang Ruixuan (female), Fang Maoxuan (female) and Xu Dezhen (female).

When you join the league, you must take an oath. The oath is "resist Japanese traitors, avenge, unite as one, and defeat the enemy to govern the country." In addition, reading the "group training" clause is mainly to resolutely resist Japan and kill well. The head of the team, Zeng Che, is composed of an organization officer, an action officer, a publicity officer and a traffic officer. Li is in charge of organization and action.

Anti-regiment training. The leader of the women's team is Fang Maoxuan, followed by Liu Yunhua, Jason and Zhang. The male battalion chief is Li, and the squad leaders are Yuan, Zhong, Zhu Zongliang and Xia. The training of the League members is mainly discussed through the team leader and the pamphlet compiled by the Anti-Union Association, including the situation in War of Resistance against Japanese Aggression, how to avoid the enemy's nails, how to deal with the enemy's capture and so on. Assemblies are usually held in members' homes, and sometimes the platform roofs of buildings are used. In order to facilitate action, members were also arranged to memorize car numbers and investigate traitor activities.

1in the spring of 939, the number of anti-union members increased, and Zeng Che and Li decided to set up a backbone anti-union training class at Chongren Primary School in Chongren, Baoding Road. Nominally a cram school. On the surface, Song teaches English, while Xia teaches Chinese. In fact, Li gave a speech on the situation in War of Resistance against Japanese Aggression, matters that members should pay attention to, principles of action, and confidentiality system. Shui Zongji talks about making time bombs: Zhao and his wife talk about the structure and use of guns.

It is stipulated to exercise in the gymnasium of the People's Hospital in the morning. Each training lasted for two weeks, but it was suspended for fear of attracting the attention of Japanese and puppet agents.
