Simplified Chinese: Worship of the Supreme Deity: The ceremony of the Great Emperor Zhen Wu is held on the 3rd day of the 3rd lunar month. It is said that originally, in the 3rd year of Emperor Chongzhen's reign (1630), when the ancestors migrated to Jing'an, they brought the statue of the Great Emperor Zhen Wu from the mainland and built a small shrine here, known as the "Upper Deity Temple". After the middle period of the Qing dynasty, the Jade Emperor enshrined it as the "Northern Celestial Hall".
