Hong Kong is a huge city of 7.5million people and one of the wealthiest on Earth.

Known as a business hub, the city attracts some of the wealthiest and most talented people to work in its huge economy.

In recent years, images have emerged of these tiny homes where an estimated 200,000 people have lived.
