Don't take this as normal history.
First Emperor of Qin: "What? My Qin dynasty fell in its second generation? That damn Hu Hai and Zhao Gao? No problem. Just watch me turn things around."
Emperor Wu of Han: "My temple name is Emperor Wu? So that's what my posthumous title was! I thought I misheard when I had the crown prince killed in my later years? Don't worry, I'll handle that properly."
Zhu Di of the Ming dynasty: "My temple name was later changed from Taizong to Chengzu, while my posthumous title remained Emperor Wen. What? The Manchus stole my realm? Unforgivable! And that Li Zicheng, and even Zhu Qizhen, who I hear is my great-grandson. Damn it!"
Emperor Wu of Wei: "The dynasty fell after three generations, and I only got my title posthumously! That Sima family, I'll kill them and take their wives."
Zhao Kuangyin, founding emperor of Song: "What? My younger brother will succeed me, and later generations will say that my Song dynasty was rich and cultured but got bullied by the Liao and others until we called them daddy!"
