In the past, it was common in Hakka society for families sell their daughters into other homes where the girls would be betrothed to a son but in fact served more as a servant. It was generally thought that to get daughters out of the house and turn them into hard-working daughters-in-law was a good deal.
過去的客家社會，互相鬻女為童養媳是普遍的情況，一般認為將女兒早日送出去換回任勞任怨的媳婦，是很「划得來」的作法。
