Since March 1967, two factions gradually formed among troops and civilians in Guangxi, China, with one faction (known for short as "the United Headquarters") unconditionally supporting Wei Guoqing—then the Chairman of Guangxi and a high-ranking CPC official —to direct the Revolution of Guangxi, while the other faction (known as "4.22") opposing unconditional support, asking Wei to do self-criticism first.
