Beijing's grand scale is truly dumbfounding. The speed of its coming economic growth poses challenges to its water and power supplies, air quality, and natural environment, as well as the well-being of its ancient buildings and cultural artifacts, which date back thousands of years.
北京規模令人咋舌，可以想見，未來經濟快速成長後，對水電供應、空氣品質、生態環境，乃至於千年古蹟的維護，都將造成嚴重挑戰。
