Passage 11-28

凡爲客之道, 深則專, 淺則散; 去國越境而師者, 絕地也; 四達者, 衢地也; 入深者, 重地也; 入淺者, 輕地也; 背固前隘者, 圍地也; 無所往者, 死地也.

The way of invasion: deep penetration unifies; shallow penetration scatters. - Crossing borders into another state—isolated ground - Roads extending in four directions—intersecting ground - Deep penetration—critical ground - Shallow penetration—marginal ground - Strong positions behind, narrow passes ahead—surrounded ground - Nowhere to go—deadly ground
