翻译“在春节人们常常吃鱼，并剩下一些，因为这样能‘年年有余’”

At Spring Festival people often eat fish and leave some so that they will have sth left over every year. (In Chinese "鱼/fish" and"余 /left over" sound the same,so "niannianyouyu" means "have sth left over every year."

In the Spring Festival, people will leave some fish uneaten when they have fish, for this means vocally "something left" for every year.

Chinese New Year people often eat fish, and the rest, because this can be 'more than year after year'
