《资治通鉴·汉纪·汉纪四十九》
然而时间有同有异，形势有可有不可，所以谋略有得有失，事情有成功有失败，不能等量齐观。
然而时有同异，势有可否，故谋有得失，事有成败，不可齐也。
“However, the times vary, and the situations are different. Therefore, strategies and tactics can be effective or ineffective, and campaigns can end in success or failure. They cannot be treated as the same kind.”
