The high-speed railway network being created across China reduces travel times so much it's often quicker to go between cities than between two places within one city, e.g. only 30 minutes Beijing to Tianjin, or 3 hours Wuhan to Guangzhou, one section of which is now the fastest railway line in the world. Perhaps soon all of mainland China could be considered as one city.
