小年到十五 春節天天有講究

大年初五：艮牛耕春

The fifth day is also called the "day of cow". According to Chinese folklore, the first seven days of the 1st lunar month are respectively called "day of chicken", "day of dog", "day of pig", "day of sheep", "day of cow", "day of horse" and "day of man". When creating all living beings on earth, Nu Wa, a goddess in Chinese mythology, created the six creatures before human beings.
初五也被稱為“牛日”。民間傳說正月頭七天分別是“雞日”、“犬日”、“豬日”、“羊日”、“牛日”、“馬日”和“人日”。中國傳統神話中的女神女媧在創造凡間生物時就是遵循了這個順序，在創造人類之前先創造了這六種生物。

The fifth day is also the God of Fortune's birthday and people will celebrate this day with a large banquet. This day is also commonly known as the Festival of Po Wu, literally breaking five. According to custom, it is believed that many New Year taboos can be broken on this day.
初五還是財神的生日，人們會舉辦盛宴以示慶祝。這天也被稱為“破五日”，字面意思是打破數字五。根據習俗，許多新年禁忌過此日皆可破。
