Chen Xi had also read some military strategies. In fact, how should I put it, these strategies are actually a summary, a kind of experience, but this experience doesn't necessarily suit you.
Military strategies are meant to be learned and applied flexibly, rather than being studied rigidly. This stuff values talent the most. To put it simply, it's normal for different people's strategies to conflict with each other. Even if those who wrote these strategies are renowned generals or ministers, it's no exception, because they all wrote based on their own times and their own experiences.
It was mentioned before that everyone is different, and each person's cognition also represents a kind of insight, marked with their own imprint.
