Atu Lie'er Village, located in Zhiermo Town, Zhaojue County, Liangshan, Sichuan Province of China is called the "Cliff Village", as its more than 500 villagers live on a cliff, where the traffic conditions are very bad and villagers need to climb nearly 800 metres if they go outside of the village. China Telecom Liangshan Branch and Zhaojue Branch overcame traffic difficulty and conducted network investigations there in September and November 2016. The mobile communication and wired broadband networks were finally fully built and opened at the end of December. Now, the Cliff Village has communication access to E-surfing 3G/4G, 100 Mbps optical broadband, high-speed Wi-Fi, Internet Protocol television and video call services, having the same Id level as cities.
