In traditional Chinese custom, 回娘家 (returning to the bride's family) is an important ritual, especially on the second day of Chinese New Year (大年初二). The counterpart is 婆家 (pójia), the husband's family home.
usage
家 is pronounced as a neutral tone (jia) here, not jiā. This is common in compound nouns: 娘家, 婆家, 人家.
