Shanghai's mass migration

The video discusses the massive migration of people from rural areas to urban centers in China, focusing on Shanghai. Over the past decade, millions have moved to Shanghai, making it one of the world's most populated cities. This migration is driven by farmers seeking better economic opportunities and a higher standard of living. However, the influx of people strains Shanghai's resources, leading to increased traffic, pollution, and demand for housing.
