One rescue worker in Beichuan, Luo Tanfei, says his team, which includes sniffer dogs, has saved 10 people in different locations since the huge earthquake struck the region Monday.
Sniffer dogs are searching for dozens of people who are feared buried under mud and rubble after their houses were washed away in the town of Manizales.
