As a researcher working for a medical institute in Zhongshan, Guangdong province, Yang Nan needs to visit Shenzhen for academic exchanges frequently, usually by driving for more than two hours.
"There were always traffic jams on the highway, although the distance between Shenzhen and Zhongshan is not much," said Yang.
The transportation situation between Zhongshan and Shenzhen, located in the western and eastern estuary of the Pearl River, respectively, improved significantly since Sunday. It now takes less than one hour for a cross-city bus between the two cities along the newly opened Shenzhen-Zhongshan Link.
