Origin Story
话说公元229年，孙权称帝，国号吴，建都建业。彼时，辽东太守公孙渊欲与东吴结盟，孙权便封他为燕王。然而，公孙渊却出尔反尔，不仅没有履行盟约，反而杀害了吴国派去的使臣。消息传到孙权耳中，他勃然大怒，大发雷霆，恨不得立刻率兵渡海讨伐公孙渊，以泄心头之恨。但经过众臣的劝谏，孙权最终还是冷静下来，采取了更加稳妥的策略，最终平定了公孙渊的叛乱。这个故事告诉我们，即使面对巨大的愤怒和不公，也要保持冷静，才能做出最明智的决策。
In 229 AD, Sun Quan became emperor, establishing the Wu Kingdom with Jianye as its capital. At that time, Gongsun Yuan, the governor of Liaodong, wanted to form an alliance with Wu. Sun Quan appointed him King of Yan. However, Gongsun Yuan went back on his word, not only failing to uphold the alliance, but also killing the envoys sent by Wu. When Sun Quan heard the news, he flew into a rage, wishing to immediately lead his troops across the sea to punish Gongsun Yuan and vent his anger. But after being advised by his ministers, Sun Quan finally calmed down and adopted a more cautious strategy, eventually suppressing Gongsun Yuan's rebellion. This story teaches us that even in the face of great anger and injustice, maintaining calmness is crucial to making the wisest decision.
