The Chinese wife/gf keeps you grounded as fuck. No shits how much you made yesterday or last month, every day is 0.
She won't care if you give the house a set of staff, maids, nannies, and a driver, she will still remind you that your role is x, y, and z and that you owe it to the famiy to maintain a high standard of living and to give your kids a life one degree higher than your upbringing
The benefit "legacy" wise is that your kids are not soft, will absolutely get their physical and mental shit kicked in creating resilient little bastards for the next generation.
Business wise, she handles all the networking and socials and keeps you from being locked in too much in your cave or at the office. Every "casual" lunch or catch up is an opportunity to connect or size up the competition and keep you in the "good graces" of the family/clan.
She also gives no fucks really if you have 1-2 other women provided discretion is exercised.
Most importantly, a legit wife of Chinese descent is gangster. They will be there when you had nothing to your name, saw potential, and invested in you when no one else did. That or they steal you from another woman who didn't appreciate you.
