Tian'anmen Square was constructed as an entryway to the Forbidden City and was a close to the emperor as commoners were allowed. Expanded to four times its original size by Chairman Mao, the square can now hold a million people. It has always been the site of celebrations and gatherings including some praising the government and some not.
Nowhere in the Chinese Empire did the power of the emperor show as magnificently as at the Forbidden Palace. It gets its name because commoners for forbidden to enter. The Forbidden City was a luxurious home for the Son of Heaven, an impenetrable fortress to protect him from his many enemies and a world unto itself.
