In order for a man to marry they need to own their own home & have a decent car. This is the societal norm in today’s China, without these things the women’s parents will not approve & they are still a confucianist society to a point, so eloping is quite rare. Now in Shanghai the home owning part is not so easy :-) Though the article is not great, because the “wealthy” part doesn’t make much sense.
(wealth starts with owning a large home, while driving a “Benz”)
