Chinese New Year, also known as the Spring Festival is the main Chinese festival of the year.
As the Chinese use the lunar calendar for their festivals, the date of Chinese New Year changes from year to year. The date corresponds to the new moon. In 2014 it will be on January the 31.
It is customary to offer foods that symbolize prosperity, wealth, and good health when they have the money to spend for the celebration. This goes in observing superstitious beliefs or traditions, since it is also their traditions for Chinese New Year to avoid things that could bring bad luck.
