The view of a 190-meter-deep shaft in Maluan Mountain that has become operational. The shaft, built for ventilation of a 7.9-kilometer tunnel on Pingshan-Yantian Passage, has a 15-meter internal diameter, which is reportedly the largest of its kind in China. Extending some 11.25 kilometers, Pingshan-Yantian Passage has two overpasses, 17 bridges and the super-long tunnel in Maluan Mountain. Upon completion of the passage, it will take just 10 minutes to travel from Jinlong Boulevard to Pingshan Boulevard. Liu Yujie
