小年 Little New Year/Minor New Year

2. House cleaning 
扫尘土

Between Laba Festival, on the eighth day of the last lunar month, and Little New Year, on the twenty-third day, families throughout China undertake a thorough house cleaning, sweeping out the old in preparation for the New Year. 从腊八到小年这段时间，中国大部分家庭都会彻底清扫房屋，“辞旧迎新”。

According to Chinese folk beliefs, during the last month of the year ghosts and deities must choose either to return to Heaven or to stay on Earth. It is believed that in order to ensure the ghosts and deities' timely departure people must thoroughly clean both their persons and their dwellings, down to every last drawer and cupboard. 
根据中国民间习俗，鬼魂和神灵都要在腊月选择返回天上还是留在人间。为了保证“他们”及时离开，人们必须彻底进行清扫，包括个人卫生和住所，抽屉和碗柜的犄角旮旯也都要打扫干净。
