2022 is the Year of Renyin, which is the Year of the Tiger in the Chinese zodiac.
The Year of the Tiger is determined based on the traditional Chinese calendar. The "Tiger" in the zodiac corresponds to the Yin of the twelve earthly branches. The Year of the Tiger is the Yin year, and every twelve years is a cycle. For example, 2022 in the Gregorian calendar basically corresponds to the Year of the Tiger, that is, the Year of Renyin.
The tiger ranks third among the twelve zodiac animals, and belongs to the "Yin" in the twelve places. Therefore, the "Yin hour" among the twelve hours of the day is also called "Tiger hour" from 3 a.m. to 5 a.m. .
