Wangfujing Commercial Shopping Street, the 700-year-old Wangfujing( the Well of the Prince's Mansion) Street or Golden Street, one of China's oldest and most famous commercial areas, was meant to be well-known in the world through the renovation, look brand new to people on September 11, 1999 when it opened to the public. The Wangfujing Street lives up to its glorious past, but with a new look. To give it a new look they completely got rid of the street's poor infrastructure at a price of over 1 billion yuan (US$120.5millon). The new infrastructure can sustain the commercial area of 300 square metres to run smoothly for 50 years, with specially designed supplies o electricity, water, gas, communications and transportation. The street came into being in the Yuan Dynasty (1279-1368) more than 700 years ago. Wangfujing Street is said to have received its name in the Ming Dynasty more than 500 years ago. One of emperors was said to want all his 10 brothers to build their mansions in the place now known as Wangfujing so as to make it easy for him to keep a wary eye on them for fear that they might pose a direct threat to him. Therefore, the street was then named Shiwangu, meaning mansions for 10 imperial brothers. Nowadays, the street is one of the busy shopping areas in Beijing.
