Rescue teams including firefighters had been sent to 16 townships.
Four people were killed and another 24 injured when an earthquake shook southwestern China, local authorities said Tuesday.
The shallow quake in Qiaojia county struck late Monday evening, the Yunnan government said on its social media account.
Video clips on China's Twitter-like platform Weibo showed shoppers taking cover in a store as boxes flew off the shelves, while students in a classroom elsewhere scrambled to hide under their desks before covering their heads with textbooks.
The quake hit near the city of Zhaotong, which has a population of over six million, and registered 5.0-magnitude, according to China's government seismology authority.
Around 600 rescue workers have been sent to the disaster area, the Yunnan government said, including firefighters and soldiers from the local division of the People's Liberation Army.
Videos on social media showed rescue workers combing through rubble and streets littered with fallen tiles and concrete.
Residents could be seen stepping over debris as they left buildings, and trying to avoid rocks that had fallen on a road while riding a motorbike.
China is regularly hit by earthquakes, especially in its mountainous western and southwestern regions.
A strong 6.0-magnitude earthquake in Sichuan province last year killed 13 and injured nearly 200 people, damaging a large number of structures.
A powerful 7.9-magnitude quake in Sichuan in 2008 left 87,000 people dead or missing.
