From a historical point of view, Emperor Kangxi of 1703 won several battles and made brilliant achievements in economy, science and technology and culture. The purpose of building the summer resort is to show his confidence in the future goal-"eternal association". Therefore, Kangxi personally inscribed the inscription, and wrote the word "avoid" as "avoid" (one more horizontal under the Xin word), deliberately writing more. No one doubted that he had written a typo, but it attracted many knowledgeable people to guess his mentality at that time. In fact, it can be said that this is also an accidental expression of self-confidence after Kangxi leveled San Francisco and turned his focus to the northern frontier.
According to historical records, Emperor Kangxi deliberately added a sum of money, but he thought: "This is to avoid summer, not to take refuge." It turned out that the emperor was unlucky and avoided the word "escape", so he added a horizontal line with a stroke of a pen, so there was no meaning of "escape".
