Guade's calligraphy

If you don't take your shoes, Li can't be crowned. This means that after passing through Gua Tian, you can't bend down to lift your shoes. Don't raise your hand to tidy your hat after passing under the plum tree. This is a metaphor to avoid causing unwarranted suspicion.

Watermelons are everywhere in Gua Tian. If you just walk here and your shoes are scattered all over the floor, it may be misunderstood as stealing watermelons. Plum trees are covered with countless fruits. If you walk under a plum tree, your hat happens to be crooked. If you reach out to tidy your hat, it's easy to be misunderstood as stealing plums.

When passing through Gua Tian, don't bend down to lift your shoes, even if you drop them. Walking under the plum tree, don't raise your hand even if your hat is crooked, so as not to be suspected of stealing melons and picking plums. Its extended meaning refers to all places that are easy to arouse suspicion, and it is a metaphor to avoid causing unwarranted suspicion.

The allusions of Guatian and Li Xia

Tang Wenzong, a great calligrapher in the Tang Dynasty, was Liu Gongquan, honest and eloquent, and served as assistant minister of the Ministry of Industry. At that time, an official named Guo Ning sent his two daughters to the palace, so the emperor sent Guo Ning to Postal Ning (now Postal County, Shaanxi Province) to be an official, and people talked about it one after another.

The emperor asked Liu Gongquan about it: "Guo Ning is the stepfather of the Empress Dowager, and he is a general. He hasn't made any mistakes since he became an official. Now, what's wrong with making him the first mate in this small place? "

Liu Gongquan said: "According to his contributions and achievements, it is reasonable to send him to be a big official, but everyone who talks about it thinks that he got this official position because he gave his two daughters to the palace."

Tang Wenzong said: "Guo Ning's two daughters went to the palace to accompany the Queen Mother, not me." Liu Gongquan replied, "How can people tell Li's suspicion?"
