In March 2023, it was an auspicious day to decorate and tear down the wall.

Auspicious days of the zodiac are divided into big auspicious days and small auspicious days. The zodiac day is a row of twelve satellites, headed by the moon. Because it is not universal, it is called Xiao Huang Dao Day. Six days of the ecliptic, six days of the underworld: construction, fullness, peace, closure, black, elimination, danger, determination, adherence to the yellow, success, opening, closure and breaking.

The auspicious day of the zodiac is a unique word in China's traditional calendar "Yellow Calendar", which refers to a day when everything is suitable. Among the twelve zodiac signs, "Qinglong, Tiande, Yutang, Siming, Tang Ming and Jingui" are called "Six Zodiac Days" (the "Clear Danger, Fix, Hold, Achieve and Open" on the twelfth duty day is called "Little Zodiac Day"). The six gods of the zodiac are on duty, everything is appropriate, and evil spirits are not avoided, which is called "auspicious day of the zodiac".
