Shenzhen is a major manufacturing centre in China. One highrise a day and one boulevard every three days is one famous line referring to Shenzhen in the 1990s. With 13 buildings at over 200 metres tall, including the Shun Hing Square (the 9th tallest building in the world), Shenzhen is a marvel of lights after sunset.
Shenzhen is home to some of China's most successful high-tech companies, such as Huawei and ZTE. A number of foreign IT companies also have facilities in the city - Foxconn has a manufacturing plant based in Shenzhen where they make most of the iPods and laptops for Apple Computer. It appears to be shipping a large majority of the new Intel-based machines at this stage. Shenzhen City Commercial Bank is also based in the city.
