AFTER a 11 weeks of lockdown, people in Wuhan went outdoors and by the thousands boarded the first trains and planes leaving Wuhan as outbound travel restrictions were lifted Wednesday. Some 2,800 people arrived in Shenzhen by train from Wuhan on Wednesday, while 270 left Shenzhen for Wuhan. In the air, the first flight from Wuhan to Shenzhen landed at Shenzhen International Airport at 9:36 a.m. More than 400 passengers from Wuhan had body temperature checks and presented their green QR code and paperwork showing they were not a health risk before they were allowed to disembark.
