It is a metaphor for short-sightedness and lack of foresight. Wait for the opportunity to attack from behind. It is also a metaphor for having worries about the future. It tells us that when considering problems and handling things, we must think deeply and consider the consequences, and do not just focus on immediate interests and ignore future consequences.
