History has too many regrets and imperfections. We often fantasize about whether the Qin Dynasty would continue to exist if Fusu had ascended the throne, whether the Tang Dynasty could have gone further if Emperor Ming of the Tang Dynasty had not become mediocre in the second half of his life, whether the tragedy of Yashan would have been avoided if Emperor Gaozong of the Song Dynasty had believed in Yue Fei, whether the Age of Discovery would have been opened by us if Zheng He had traveled more to the West, and whether the Opium War would not have happened if Emperor Qianlong had become curious and yearning for the outside world when receiving the Macartney delegation. These are the regrets of the Chinese nation. Today, when we read these histories, we feel sad, regretful and confused. Entering that era, there are no time travellers, no history is spoiled, there is only a small flash, think about another possibility of history, and explore another road at the fork in the road.
