What are the three wonders of Wuhou Temple?

According to these three wonders, there are two theories: one is that Hua Rong, governor of Sichuan in the tenth year of Hongzhi in Ming Dynasty, wrote a cloud on the tablet: "People distinguish by their writings, but the writings of Wuhou are immortal." This is a compliment to Zhuge Liang's achievements and Liu Pei's words, and it is called "Three Musts". The other is Pan, a juror of Huayang in the ninth year of Daoguang in Qing Dynasty, who thinks that the skills of writing, calligraphy and seal cutting are immortal.
