According to "Huayang County Records", "Hongpailou Fort is ten miles south of the county seat. During the Ming Jiajing period, Shu Wang built a square here, named Hongpailou." According to legend, there were two archways in Nanbei Street of Hongpailouchang Town at that time. The purpose of Wang Jianfang in Shu is to welcome Tibetan compatriots who come to Tibet to give gifts and do business, so according to Tibetan customs, it is painted red. There are three longmen in the archway, and the dragon and phoenix patterns are engraved on the doorposts. The middle gate is open to vehicles and pedestrians on both sides. Into the archway, there are colored streets on both sides, and there is a red building across the street in the field. There is a red temple at the end of the field (south street), and there is a row of red buildings in the temple. It's really a red chamber on the street, a red chamber on the street. Therefore, the Red Card House is also called the Red Card House. As a landmark building of Hongkawu Town and a symbol of national harmony and commercial prosperity, it stands on the street and is spectacular and famous. -It's a pity that an ancient scenic spot like Zeng Guangyao collapsed.
