Why is there no high-speed exit in Maling Town?

There is no construction. Maling Town is located in the west of Wuming County under the jurisdiction of Nanning City, Guangxi Zhuang Autonomous Region, and there is no high-speed exit. China's expressways refer to those planned, constructed, operated and managed in People's Republic of China (PRC). China's expressways started late and developed rapidly, forming expressway transportation corridors extending in all directions. China's expressways are multi-lanes, allowing cars to travel in different directions and in different lanes, and all access is controlled.
