When was the Yuchan Palace in Wenbi Peak, located in Ding'an, Hainan, built?

Wenbi Peak Taoist Cultural Garden and Hainan Yuchan Palace promote Hainan’s history, culture and local culture, including Taoist culture. This not only shows that Hainan’s history, culture and local culture are an integral part of Chinese traditional culture , and shows that Hainanese are participants and creators of Chinese traditional culture. Taoism is a native religion native to my country. Taoist culture contains rich traditional cultural connotations in many fields in Chinese history. Hainan Taoist culture has a long history. In the history of Hainan's development, as immigrants from the Central Plains continued to move to Qiong, Jingchangguan was built in Ganfen County (today's Changjiang County) as early as the second year of Qianfeng (667) by Emperor Gaozong of the Tang Dynasty. The establishment of Jingchangguan not only satisfied the spiritual and cultural needs of immigrants from the Central Plains who moved to Qionghai, but also served as an example of the influence of Central Plains culture on Hainan. During the Song and Yuan Dynasties, due to the initiative of the emperor, palaces and temples were set up all over Hainan prefectures (military) and counties. In the first year of Xuanhe of the Song Dynasty (1119), Emperor Huizong of the Song Dynasty issued the "Edict of Shenxiao Yuqing Wanshou Palace". This edict was engraved in thin gold script with the calligraphy of Emperor Huizong of the Song Dynasty. It is still erected in the Wugong Temple in Haikou. It is the only remaining edict in the country. A complete Xuanhe Imperial Monument is a very precious historical relic. Taoist culture has a very extensive influence on Hainan's local culture and is deeply integrated into Hainan's folk culture. To this day, many folk festivals, sacrifices, and folk activities all contain the flavor of Taoist culture.
