Three divisions and one brigade, the main attack direction was Hainan. According to this directive, the guerrillas in northern Guangdong, eastern Guangdong, Hainan and southern Guangxi respectively gathered in western Guangdong, reorganized, waiting for the opportunity to launch a major counterattack.

In this way, a well-equipped unit, extremely good at fighting in the tropics, gradually formed in the desolate western region of Guangdong, but the Japanese army suffered from severe kidney failure and could do nothing. They tried to suppress it many times, but were tormented by the 56th Army armed with type 63 automatic rifles and 40 rocket launchers, and more than 3,000 people were killed. by mines. After sinking six ships, the Japanese army was so scared that they no longer dared to mention the raid, they stayed in Zhanjiang like a turtle, and no matter how provocative the guerrillas were, they would not take action if They can't go out! ,
