Is Weihai Gu Mo Tunnel not easy to walk?

Yes Gu Mo Tunnel was built at 1995. Due to the limitation of technology and materials at that time, after nearly 20 years of operation, the tunnel appeared problems such as water seepage, poor lighting conditions and poor ventilation, which adversely affected traffic safety, resulting in difficulty in walking and poor road conditions. Weihai has beautiful scenery and four distinct seasons. It is a tourist summer resort with mountains and seas.
