The Chinese city of Shenzhen is often used as an example to illustrate the rapid transformation many Chinese cities have undergone in the past few decades. At one time a small fishing community of about 30,000 people, Shenzhen has become a massive city with a population exceeding 12 million. As the population began to rise, so too did the buildings. At the end of 2016, Shenzhen had eight buildings over 1,000 feet tall already constructed or topped out and dozens more over 500 feet tall.
