Yaoyinggou in Wangqing County of China was where the KPRA headquarters was located in the first half of the 1930s.

At that time, the Japanese aggressors were frantic in "punitive" offensives against guerrilla zones.

They forced residents to live in "internment villages" and tightened the "collective watch system" in a bid to leave guerrilla zones isolated completely from communities, while launching "surrender campaign" to undermine the revolutionary ranks.

To cope with the situation, Kim Il Sung at the meeting of KPRA military and political cadres set forth a new line of relinquishing the guerrilla zones and launching operations of large units in wide areas.

The line was a justifiable one which made it possible to turn adversity into favorable condition.

The validity of the line was clearly proved in the ensuing KPRA's anti-Japanese armed struggle and the Korean revolution as a whole.

After the Yaoyinggou meeting, the KPRA expanded the armed struggle in vast areas in the homeland and Manchuria to overshadow the enemy's numerical and technical superiorities, frustrating its attempt to stifle the KPRA units.
