Why didn't China Telecom go online when it arrived in Linqu?

Telecommunication network has no coverage. Because the telecommunication signal is sent from the base station, the signal intensity gradually weakens with the transmission distance, and it cannot be reached due to the barrier of buildings, structures and mountains. Established on April 27th, 1995, China Telecom is a state-owned super-large communication backbone enterprise and a global partner of Shanghai World Expo. It has been selected as one of the "Top 500 Enterprises in the World" for many years, mainly engaged in comprehensive information services such as fixed telephone, mobile communication, satellite communication, Internet access and application.
