The 23rd day of La Yue in north China and the 24th day of the month in south China are the Xiao Nian Festival on the Chinese lunar calendar. Xiao Nian is also called "Little (Chinese) New Year," symbolizing the start of the Spring Festival.
In one of the most distinctive traditions of the Little New Year is the burning of a paper image of the Kitchen God, dispatching the god's spirit to Heaven to report on the family's conduct over the past year.
The Kitchen God is then welcomed back by to the home through the pasting of a new paper image of him beside the stove. From this vantage point, the Kitchen God will oversee and protect the household for another year.
Most of the offerings are sweets of various varieties. It is thought that this will seal the Kitchen God's mouth and encourage him to only say good things about the family when he ascends to heaven to make his report.
