Will China become Eastern Orthodox?

Currently in China, you see a crisis of birth rates and the marriage/dating market. Chinese women are too demanding in marriage and often demand high bride prices, and there’s an oversupply of men. Meanwhile, Russia has an oversupply of women, as a lot of their men have been dying in Ukraine. Because of this, there’s been an uptick in Chinese men marrying Russian women.

Could Russian brides convert their Chinese husbands to Eastern Orthodoxy? And could this have a downward effect of spreading Eastern Orthodoxy amongst their children and eventually among the entire population, converting it into an Eastern Orthodox country?
