  1. 可以往難以返曰挂
  2. 挂形者敵無備出而勝之敵若有備出而不勝難以返不利
  3. 我出而不利彼出而不利曰支
  4. 支形者敵雖利我我無出也引而去令敵半出而擊之利

4. Ground which can be abandoned but is hard to re-occupy is called entangling.

5. From a position of this sort, if the enemy is unprepared, you may sally forth and defeat him. But if the enemy is prepared for your coming, and you fail to defeat him, then, return being impossible, disaster will ensue.

6. When the position is such that neither side will gain by making the first move, it is called temporizing ground.

7. In a position of this sort, even though the enemy should offer us an attractive bait, it will be advisable not to stir forth, but rather to retreat, thus enticing the enemy in his turn; then, when part of his army has come out, we may deliver our attack with advantage.
