Step into the subway multiverse

The podcast explores the transformation of China's subway stations into commercial hubs to offset operational costs, driven by increasing commuter demands and the financial strain of maintaining these systems. Subway stations in cities like Guangzhou, Wuhan, and Shenzhen are incorporating supermarkets, fresh produce markets, sports facilities, and connections to cultural venues. While Hong Kong's subway system is profitable, most mainland Chinese systems, including those in major cities, struggle to break even due to low fares and high construction costs. The discussion also covers the dangers of third-hand smoke, defining it as toxic chemical residue from tobacco smoke that lingers on indoor surfaces for extended periods, causing DNA damage and health risks. New regulations, like those in California requiring disclosure of third-hand smoke contamination in home sales, and stricter smoking bans in Shenzhen, aim to address this often-overlooked health hazard.
