The Wuhan Tianhe International Airport has just opened for domestic flights (from April 8). While many are saying this is a significant milestone and a sign of hope, others are cautiously observers, checking if all safety meaures are in place to prevent another wave of infections. The city just emerged from a 76-day lockdown on April 6. It is part of China's gradual lifting of quarantine across the country. Last week, a mountain park saw 20,000 visitors in one day.
