In Northeast China, there is a custom of Labang. If the husband is unable to maintain his family's livelihood or suffers great difficulties, he will hire another husband to maintain the family's life with his wife's consent.This custom has been around the three northeastern provinces for a long time and was even more prosperous during the Republic of China. Many areas in the northeast became accustomed to it and did not think there was anything wrong with it. The two husbands would come together to drink every day, and the three of them were frank in bed.
