Tai Sui is the "Guardian God of the Year". It is believed that this governs all the fortunes of a particular year.
TheTai Suiconcept is based on Jupiter’s 12-year orbital cycle which determines the 12 signs of the Chinese zodiac.
The star that opposes Jupiter during each lunar year is personified as a heavenly general, cycle god, Grand Duke of Jupiter or TaiSui.
In case you are wondering, Chinese lore is often linked to astrology. Hence, it is not uncommon for the deities to be personified as stars and constellations in the night sky.
There are 60Tai Suis which is derived by combining the 12 signs with the five Chinese elements of fire, earth, metal, water and wood.
