In a Communicative Ground by Sun Zi
English: An area that is easily accessible to me and the other side is considered as a communicative ground. On a communicative ground, the priority is to occupy a high and sunny position that is convenient and beneficial for overseeing the supply routes for food and rations. In this way, advantages in battle are gained.
Modern: 我可以去、敌可以来的地域，叫做“通”。在通形地域，要抢先地势高而又向阳，沟通并保护粮道，这样与敌交战就比较有利。
Original: 我可以往，彼可以来，曰通。通形者，先居高阳，利粮道，以战则利。
