Director-General Chen commented that the Qingshui Ghost Cave in Aofeng Mountain Park is a popular tourist destination, attracting a lot of visitors daily. However, since the tunnel is a closed space, it was temporarily closed before the Chinese New Year in response to the worsening pandemic conditions to prevent droplet transmission or contact infection. In light of the stabilizing pandemic situation in the country and people's need for outdoor recreation, the cave is now open to the public.
Director-General Chen pointed out that the Hengshan Tunnels on the northeast side of the Aofeng Mountain Park in Qingshui District was constructed in 1944. The underground military tunnel built during the Japanese colonial period is 420m long, and the sprawling tunnel network is warm in winter and cool in summer. The impregnable tunnel structure consists of cobblestones, rebar and concrete. In 2017, the tunnel was closed due to inadequate safety equipment and a renovation was implemented by the Construction Bureau to install lighting, firefighting, ventilation, and surveillance equipment. The tunnel was reopened in April 2019. Although it no longer serves military purposes, visitors can still feel the tense atmosphere of the war decades ago.
