小年到十五 春节天天有讲究

On the 29th day of the 12th lunar month people visit the graves of their ancestors to honor their memory. It is said Spring Festival originated in the Shang Dynasty (c. 1600 BC-c. 1100 BC) from the people's sacrifice to gods and ancestors at the end of an old year and the start of a new one.
腊月二十九，人们动身扫墓，拜祭祖先。据说春节始于商朝（公元前1600年至公元前1100年），那时人们在辞旧迎新之际祭祀神灵和祖先。
