Is it better to live in Shanghai or Kuala Lumpur?

The two cities are not comparable in price, environment, wage level, population and cultural diversity. Kuala Lumpur lags far behind Shanghai except that the environmental quality is better than Shanghai and the price is not as high as Shanghai. Besides, if you want to live in Malaysia, you must also be proficient in English and Malay. This is a multi-ethnic country with a mixed population and cultural conflicts, and some Malays have conflicts.
