4. That the impact of your army may be like a grindstone dashed against an egg – this is effected by the science of weak points and strong.

兵之所加如以碬投卵者虛實是也

Sun Tzu

In order for an army to be successful in battle, it must be able to use the “science of weak points and strong” to its advantage. This means that the army must be able to identify the weaknesses of the enemy and focus its attacks on those points, while also being aware of its own strengths and using them to defend against the enemy’s attacks. The metaphor of a grindstone being dashed against an egg suggests that the army must be able to effectively use its power and force to overwhelm and defeat the enemy, just as a grindstone would easily break an egg.

The effectiveness of your business strategy can be compared to a grindstone breaking an egg, which is achieved through the understanding of weaknesses and strengths.

In order to be effective, a business must be able to identify the weaknesses of its competitors and focus its efforts on exploiting those weaknesses, while also being aware of its own strengths and using them to defend against the competition. For example, a business might identify a competitor’s weak customer service as a weakness to be exploited, and focus its marketing efforts on highlighting its own strong customer service in order to gain a competitive advantage. By understanding and leveraging the strengths and weaknesses of both itself and its competitors, a business can effectively use its power and resources to achieve its goals.
