回娘家(huí niáng jiā), literally “returning to the wife’s home”, is the second day of the Spring Festival, when married couples go visit the wife’s family.
In ancient China, a woman would usually go and live with the husband’s family after getting married. It was her responsibility to look after them, managing household affairs and taking care of children. Therefore, of course, it wouldn’t do for her to run back home to her parents every other day - doing so was considered bad luck for her entire family.
This day was a rare exception.
Nowadays most couples live independently (and women can go home when they want to), but it’s still customary to visit the in-laws on this day. And of course, turning up empty-handed is a no-no, so parents all over the country are looking forward to what they call “Son-in-Law Day”
"Left hand with a chicken, right hand with a duck, a fat baby on the back".
(Lyrics of a famous song).
