Chongqing

China’s mountain megacity where a metro train passes through the 6th floor of a residential building — the Liziba monorail spectacle, Hongya Cave riverside food stalls at night, Chongqing hotpot (hotter and oilier than Chengdu’s), the Yangtze River cable car after dark, day trips to Wulong’s natural bridge system, and the 65-minute bullet train connection to Chengdu.
