According to the rural custom in Taiwan Province Province, the Christmas of Sanshanwang in Taiwan Province Province is scheduled for February 25th every year. The king of the three mountains in eastern Guangdong will travel in the first month, usually on the tenth or fifteenth day of the first month. The actual history of Sanshanwang Temple dates back to Sui Dynasty and is related to Ryukyu Islands.
According to legend, when Han Yu, a literary giant in the Tang Dynasty, was demoted as the secretariat of Chaozhou, local floods flooded and residents prayed for rain to these three mountains. Sure enough, Han Yu named them the Three Mountain Gods. In the Northern Song Dynasty, the Three Mountain Gods appeared many times to help Song Jun pacify the chaos, so Song Taizong gave them the titles of King Wade of Tsinghua (King, Scarf king of the hill), King Suning (Two Kings, Ming king of the hill) and King Hui Weihong (King of Three Kingdoms and King of Dushan), and jointly worshipped them as "Kings of Three Mountains"-the clergy were responsible for hunting and supervised the Buddha on behalf of the Sky Patrol.
