乾隆读书广泛,但也有重点。他的重点自然是那些和他担当一样角色的皇帝们。他是以欣赏的角度看李世民的。他对唐太宗有如下的评价:一是唐高祖李渊没水平,如果他将李世民选为太子的话,就不会有玄武门事件。要是李建成继位,那么,乾隆断定,唐也脱不了隋的命运,绝对短命,所以责任还在唐高 Qianlong had a wide range of readings but also had a focus. His focus is naturally those emperors who have the same roles as him. He looked at Li Shimin from the perspective of appreciation. He commented on Taizong Tang as follows: First, Tang Gaozu’s Li Yuan did not have a level. If he chooses Li Shimin as Prince Edward, there will be no Xuanwumen incident. If Li Jiancheng succeeds, then, Qianlong concluded that Tang could not take off his destiny. He is absolutely short-lived, so the responsibility is still high.
