That korean one is also pretty bullshit. The anarchists were allies with the Chinese communists and they were pretty well protected as a result. The CPC got pushed out of the area by the kuomintang and then the anarchists were dispersed by the KMT after their leader was killed.

The death of their leader was caused by the CPC getting pushed out of the area that led to his death. They literally collapsed without communists as neighbours to defend the territory nearby.

Mao was very fond of the anarchists. A lot of his rural theory was obviously inspired by them.
