Besides economic reasons (i.e. Tier 1 cities like Beijing, Shanghai, Shenzhen and Guangzhou are ‘wealthier’ than others), there are lifestyle / cultural / local language nuances that can have a bearing on how consumers live their lives / do business in these cities. Since products and services that have the strongest relevance in consumers’ lives generally do better, it’s important to ‘dig deep’ and understand how Chinese consumers differ. This will ensure that the launched product or service will have the greatest chance of success in the market at large, rather than only having a niche appeal in certain cities.
