5.Areas which are surrounded by the enemy but whose central parts are not occupied or have been recovered, like some counties in the Wutai mountain region (i.e., the Shansi-Chahar-Hopei border area) and also some places in the Taihang and Taishan mountain regions, are ready-made bases for the convenient use of guerrilla units in developing guerrilla warfare. 
6.The large guerrilla formations operating on the plains will be unable to keep on fighting there for long and will gradually have to move up into the mountains as the circumstances require, as for instance, from the Hopei Plain to the Wutai and Taihang Mountains, or from the Shantung Plain to Taishan Mountain and the Shantung Peninsula in the east.
