I'll only demonstrate this once!# #A joke: Qianlong, the “Perfect Old Man”# #The figure no discussion of Tang poetry can avoid: Li Bai, the Immortal Poet# #Confucius: The Supreme Sage and Teacher, misrepresented# #A ranking of the most useless emperors# #How the prestige of the Fengshan rites at Mount Tai declined# #The emperor who began with every advantage, yet had to beg at the city gates# #Could hybrid rice have been cultivated in ancient times?# #Every line in the history books represents one person's extraordinary life#
