It is said that there was a man named Mulian in ancient times. His mother was fierce and evil before her death, and she was locked in a cell in the underworld. When he visited the prison, he often sent food to his mother, but all the food was eaten by the jailer's kid. Later, he thought of a way to mix water chestnut, peanuts, red dates, longan, brown sugar and other raw materials with glutinous rice, cook it into sweet porridge, put it in a bowl, and then sprinkle a handful of black sesame seeds to his mother. Seeing that the porridge was black, the jailer asked, "What is this?" ?

Mulian casually replied, "This is a dirty one". (Fuzhou dialect is homophonic for "nine" and "dirty") The guards think this porridge is dirty and dare not eat it. Therefore, Ou Jiuzhou was given to Mu Lian's mother. It happened to be the 29th day of the first month, and Mulian's mother was just 29 years old this year. According to folk customs, the first month is divided into "Sanjiu", the ninth day of the first month is called "Shangjiu", the 19th day of the first month is called "Zhongjiu", and the 29th day of the first month is called "Houjiu porridge".

Later, the color of porridge became darker, and it was called "Nine Porridge" to show filial piety to mother, also called "Nine Porridge". Whether it is the 29th day of the first month or the 29th day of the twelfth month, it is a difficult year for Mulian's mother. Therefore, Fuzhou people taboo nine days and think that "nine days" is a year of adversity. Therefore, anyone who meets the age of "99" should eat peacefully, and his married daughter should also give her parents a "99" to ensure their safety and health.
