Whether working a job or starting your own business, overall, the atmosphere of interpersonal interactions in the Pearl River Delta is ultimately more tolerant and down-to-earth than in the Yangtze River Delta.

A friend who used to work at a state-owned enterprise in Guangzhou asked me recently; she was torn between two marriage prospects, both from wealthy families, only children. One was from the Yangtze River Delta, and the other was a local rich second-generation from the Pearl River Delta. She didn't know how to choose.
I first asked about her personality and her family background. She said she came from a small-town family in Chongqing, with parents running a grocery store.
After hearing that, I directly advised her to prioritize the Pearl River Delta candidate.
The main reason is simple: elders in the Pearl River Delta tend to have a more easygoing mindset, and they don’t carry an aloof attitude. It’s less likely to cause grievances after marriage. In contrast, in some areas of the Yangtze River Delta, a sense of superiority is more ingrained, and the standards and expectations for others are higher.
Look at the accent in the Wu language region—it's a bit like a Japanese accent when spoken in fragments. What do people in Shanghai call themselves? Shanghainese, right? On par with Beijing folks. Have you heard of any “Sui Ye,” “Yue Ye,” or “Shen Guan Ye” in Guangzhou? At most, there’s the “Guan-style service” or “Guan-style standards,” right?
The Pearl River Delta has always been pragmatic and low-key, valuing harmony and sincerity in interactions. Compared to putting on airs or showing off, here people value genuine relationships and living a steady life.
