If Chinese women age so “gracefully” why are Chinese men marrying Russians? No doubt they’re buying VISA’s in order to get into the country and hedge their bets. Russian women are always looking for wealthier foreign men, but I suspect the Chinese government encourages this in order to get more people into Russia in order to “influence things”.
Those “visa” marriages are strictly temporary and not based on till death do us apart. Once the visa comes through, in most cases separation follows.
