China is scrambling to help the tens of thousands of people left homeless by a huge earthquake.
The 6.6 magnitude quake struck early Saturday, hitting the city of Ya'an especially hard.
188 people are known to have been killed so far, and more than 11,000 are injured.
Authorities worry the survivors could run out of drinking water.
Local officials say their priority for now is saving lives.
