Sau, the God of Longevity, is probably the most popular deity out of the Three Star Gods Fuk Luk Sau. He represents good health, longevity, and quality, and smooth life. He is depicted carrying the Peach of Immortality, itself an auspicious symbol for long life and excellent health. The God of Longevity is also seen carrying a Dragon staff with a Wu Lou. The Wu Lou is believed to be filled with the nectar of immortality.
Place Sau on an elevated height preferably facing directly to the main door of the room, with a solid wall behind him. If that is not possible, you can place it diagonally but still facing the main door. The God of Longevity will create good Feng Shui chi that bestows upon the family with good health luck. You do not have to pray to this deity.
Do not place the God of Longevity in the bedroom or on the floor.
