China...(wow!)...

China is immense, enormous, gargantuan, mammoth, behemoth, colossal -- now multiply all those words together, and this will not give you a sense of the size and density of the space, city and people in China, particularly of Beijing. Its enormity is spectacular, breath-taking. I believe it's impossible to fathom without witnessing it yourself. Nonetheless, I offer you these pictures as a small token of explanation.

Tian'anmen Square, a pedestrian-only public space covering almost 100 acres (!!), seen from the ground:

The Monument to the Heroes and the Chairman Mao Memorial Hall (mausoleum):

Tian'anmen Square from atop the "Gate of Heavenly Peace," entrance to the Forbidden City:

The Forbidden City or Gugong (Imperial Palace) -- some of its structures dating back to Kublai Khan, but the grand plan of it wholly of the Ming and Qing Dynasties; a labyrinthine structure of over 800 buildings -- viewed from the outside. For five centuries, ordinary Chinese were not allowed to even approach the Forbidden City:
