my country's infrastructure breaks multiple records!3 high speeds connected in series in the Three Gorges Reservoir area

At 00:00 on September 2nd, the G5012 Enshi to Guangyuan Expressway Chongqing Wanzhou Xintian Xintian Xintian Xingtao Section, which was invested and constructed by the Group of the China Communications First Public Bureau Group, was officially opened and operated.
