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?"
