Shanghainese people are f***ing hollow. They rely entirely on material possessions to fill their inner emptiness because they have no real emotions to speak of. Money is what maintains their relationships 90% of the time; only 10% is genuine feeling. I recently saw some posts complaining about Shanghainese people, and I thought they hit the nail on the head.
