The Qing Dynasty Fell

History is made up of countless accidental events, but some special nodes have far-reaching impacts. For example: If Jing Ke succeeds in assassinating Qin, when will the unification of China come? If Xiang Yu killed Liu Bang at the Hongmen Banquet, would there still be the name Han? If the Xuanwu Gate Mutiny failed, would there still be a prosperous Tang Dynasty? If Yue Wumu withstood the pressure of twelve gold medals, could the Song Dynasty take back the sixteen states of Yanyun? If Zhu Biao had survived that cold weather, would there still be the Great Beijing that it is today? If Chen Mo had escaped the fire in Xiangtan City in 1854, would history have other possibilities?
