Beijing’s subway system is the longest in the world, numbering 275 miles and 227 individual stations. Its flat fare of 2 yuan (about 32 cents) is the lowest among the rapid transit systems in China and possible because of government subsidies. As tourism grows within China, a debate has arisen over proper subway etiquette; reports of physical fights and kids urinating in subway cars helped prompt a new Beijing law intended to curb uncouth habits.
