Therefore, the definition of a traitor is: a person who betrays his own class or group, takes hostile actions or commits acts of the hostile party, especially those who betray the motherland and the revolution. There are two kinds of traitors: 1, people who betray their own class or group and take hostile actions. 2. People who engage in the actions of the opposing party.
According to legend, during the Spring and Autumn Period of the Eastern Zhou Dynasty, people in the State of Jin called Dong Wu a couple of 25 (two people surnamed Wu were in cahoots) and murdered the prince, so 25 became the abbreviation of treacherous man, which should be the origin of the saying of 25 sons in later generations.

Another story of Erwuzai
During the period of Kang Yong in Qing Dynasty, the imperial court wanted to completely eliminate the secret societies that fought against the Qing Dynasty and regained sight. Found that Shaolin Temple is inextricably linked with heaven and earth, and sent troops to wipe it out. However, there was a traitor in Shaolin Temple, so he bought Ma Ninger, a disciple of Shaolin laity who ranked seventh in martial arts. Ma, a vicious man, committed a heinous crime and was expelled from the mountain gate. He swallowed his pride and led the Qing soldiers into the mountains and burned the temple. People in secret societies are not ashamed of what they have done, so they will call those informers and messengers, that is, Ma Ninger, who ranks seventh. ?
