Jianjiang basically means bandit. During the late Qing Dynasty and the Republic of China, a large number of young farmers worked in the Nanshan area in western Henan where bandits were most rampant. Every winter in the slack season, they are recruited to repair and maintain farmland irrigation projects such as terraces and ditches. These people are called "builders" locally. Once the work is reduced and there is nothing to do, the craftsman team can easily become gang bandits, so that the boundaries between them become increasingly blurred. Therefore, in Lushan dialect, bandits are collectively called "gang generals".
