1 / 5   Mud and landslides caused by flooding and heavy rain is common in China’s mountainous areas in summer. Potential earthquakes make disaster monitoring much more of a problem in Dujiangyan City, southwest China’s Sichuan Province. However, there is a group of unknown heroes who devote themselves to observing and reporting about the calamities from May to October annually, in order to protect the residents and minimize the damage. /VCG Photo

In the past nine years, he and his colleagues have stayed in the mountains, paying attention to the subtle signs of a landslide day and night. So far they have successfully alerted local villagers to evacuate before a disaster hit more than 10 times. /VCG Photo

Before the flood season, the Land and Resources Bureau will issue risk warnings, it is then the job of Mou and his colleagues to inform villagers. /VCG Photo
