Laying soil in Anlong is one of the most important fasting ceremonies in Taoism. Whenever a major Taoist fasting ceremony is held or a foundation stone laying project is held in many kind-hearted men and women's homes, the Nine Emperors Huang Zhen, Anzhen Wufang Dragon and Four Treasures Kung Fu will be disturbed, so it is necessary to hold the foundation stone laying ceremony of Anlong to pray for the protection of the Heavenly Emperor, Tai Sui and Wufang Dragon God.
