Thousands of residents have braved the scorching heat to watch helicopter demonstrations and try out military equipment at a PLA airbase near Hong Kong’s border. Military enthusiast Kin Man arrived at Shek Kong with his mother from Tai Po more than an hour before the 9am opening on Saturday. They were among the first ticket holders in line for the open day, part of celebrations marking the 29th anniversary of the city’s handover on July 1.
