It's harder being a chinese woman. To pass the family farm down, the families heir has to marry. But they keep aborting all their girl children in rural areas because they stupidly believe women can't work the land, so they have no women for their sons to marry. So they're allowing cousins to marry now (or just flat out allowing incest out in the boonies).
Others have resorted to kidnapping female tourists or women working in the city.
