With its gradual economic growth, China attaches great importance to the urbanization,however most of the rural areas are confronted with the defects of being unable to keep themselves updated with the latest information. What’s more, the communication system there are so wretched that villagers can’t get timely evacuation information if there is a sudden burst of natural disasters, which reminds us of the Wenchuan Earthquake Disaster. SPON gives the best solution of village/ enterprise PA system.
