The eleventh day of the Lunar New Year is known as the day to welcome Zigu Shen (the Purple Lady).
According to legend, Zigu was a concubine of a rich man in ancient China. The wife of the rich man killed her in the toilet due to her jealousy. The Heavenly God had compassion for her, so he made her the god of the toilet. Zigu represents all the females who groan under the oppression in the feudal society. (I’m ambivalent about the reward Zigu got in this deal.)
Traditionally, the 11th day of the Lunar New Year is when the wife’s father would invite his son-in-law to a meal at home. It not only provides quality bonding time between the two families, but also a chance to clear out the leftovers from the celebratory food for the Jade Emperor’s birthday on the 9th, so once again the left overs can be used to entertain the sons-in law.
