The chapter on momentum ends, and Sun Tzu moves to empty and full. It is the chapter on what is hollow and what is solid, their weak points and your strong ones. Its first sentence is about place and time.
Two people fighting in the same place are not in the same conditions. Who arrived first has already settled half of that day.
凡先處戰地而待敵者佚，後處戰地而趨戰者勞
fan xian chu zhan di er dai di zhe yi, hou chu zhan di er qu zhan zhe lao
Whoever takes position on the ground first and waits for the enemy is at ease. Whoever takes position late and hurries into the fight is worn out. (The Art of War, Empty and Full, translated directly)
