Xuan Tian Shang Di (玄天上帝, literally means ‘Dark/Mysterious Heavenly God’) , also known as Xuan Wu Da Di and Zhen Wu Da Di , is a powerful deity in Chinese religion. He is one of the higher ranking deities in Taoism. He is revered as a powerful god, able to control the elements and is capable of great magic. He is also the patron god of Northern China. As Han Chinese (now the modern-day Cantonese and Fujianese peoples) who migrated into the south from Hebei and Henan during the Tang-Song era brought along the deity, Xuan Tian Shang Di is also widely revered in the Guangdong, Guangxi and Fujian provinces, as well as among the overseas diaspora.
The statue of Xuan Tian Shang Di is dressed in black robes, with a turtle and a snake under his feet or in front of his seat. He holds a seven-star sword which is the symbol of the Big Dipper.
Other than eliminating disaster and killing demons, it is believed Xuan Tian Shang Di can control water and fire. He is also brings luck and prosperity to businessmen.
His birthday is celebrated on the third day of the third lunar month which is coincidently Shang Si festival, an auspicious day for blessings and to get rid of evils.
