What's the difference between life in Zhuhai and Beijing?

In Zhuhai and Shenzhen all the year round, my aunt, uncle, grandparents are in Beijing, and my home is in Shenzhen. Generally speaking, life in Zhuhai is much more comfortable than that in Beijing and Shenzhen. But the price is definitely not cheaper than Shenzhen and Beijing. Although the consumption level is not an order of magnitude, there is not much difference between Beijing and Shenzhen. Apart from the climate, Zhuhai is hotter than Shenzhen in summer and colder than Shenzhen in winter. But the weather in both cities is changeable, and it is likely to rain suddenly in one day. However, the air quality in these two cities is much better than that in Beijing. Finally, there are many people in Zhuhai, the city is much smaller and the streets are much narrower.
