Travelers arrive at Shenzhen Bao’an International Airport on Monday. The city’s railway stations, highways, and airport are bracing for a fresh travel peak as a growing number of travelers hit the road and return to work after the Spring Festival holiday, which ended yesterday. The airport expects the highest peak today. Metro Line 11, which connects to the airport, will extend its operating hours until 1 a.m. until tomorrow. Liu Yujie
