Urban planning in Shanghai is like playing with a huge Lego set. Just like how you build and arrange your Lego pieces to make a cool and organized creation, urban planners in Shanghai do the same thing, but with buildings and roads instead of Lego bricks.
But why do they do that? Well, you know how sometimes it can get very crowded when you play with many people? It's kind of the same thing in the big city of Shanghai. There are lots of people living and working there, and they need space to move around and do their things. That's where urban planners come in to make sure that there's enough space for everyone to live, work, and play.
Urban planners in Shanghai look at different things, like how many people are living in certain areas, how many buildings they need, where to put roads, and how to make sure that everyone can easily access transportation like buses and trains. They also make sure that the buildings they design are safe and won't easily fall down in case of earthquakes or other natural disasters.
Urban planning takes a lot of time, effort, and money, but it's important to make sure that everyone in Shanghai can live, work, and play in a safe and comfortable environment. By planning the city carefully, people can have a better quality of life, and the city can grow and develop in an organized and sustainable way.
