Tai Sui is a term used in Chinese astrology that refers to the God or Deity that presides over a person's zodiac sign during a particular year. Imagine Tai Sui as a big, powerful chief who sits on a throne overlooking all the other gods and goddesses.
In Chinese culture, it is believed that upsetting Tai Sui by any means, like arguments or construction works, could result in bad luck and misfortunes for the person. It could be compared to being scolded by a strict parent for misbehaving.
To avoid upsetting Tai Sui, Chinese people observe certain rituals such as wearing talismans, offering prayers, and donating to charities. It's like following certain instructions to avoid getting in trouble with mom or dad.
So, imagine Tai Sui as a strict and powerful deity, and to avoid getting into trouble, Chinese people perform certain rituals and follow instructions to stay in Tai Sui's good graces.
