A massive natural disaster hit the Sichuan province in 2008, which left about 90,000 dead or missing, and the BBC notes it also caused a landslide that killed 37 tourists. The woman was in the bedroom of her home when the landslide hit the village, and rescuers were trying to reach her, the report said.
"This is useless", villager Han Jianying, searching for missing family members, told the Reuters news agency.
The Sichuan government has dispatched more than "500 rescuers with 23 sniffer dogs and 16 life detectors" for search and rescue efforts, according Xinhua.
More than 2,500 rescuers - some digging with bare hands, some using detection devices and dogs - were looking for signs of life as industrial excavators removed rubble at the site.
At about 6 o'clock in the morning, a side of the mountain in Aba Tiberan and Qiang autonomous prefecture collapsed and made its way down to Xinmo village, blocking a 2 kilometer stretch of the river and covering 1,600 meters of road.
In Diexi, another hamlet overlooking Xinmo, corn farmer Yang Cangxin said she knew everyone in the neighbouring village.
Rescuers continued to search through mounts of rock and rubble Sunday.
In the only story of survival, Qiao Dashi, whose wife and baby also escaped, said he had woken up after 5:00 am to change his crying son's diaper when the house shook.

Council leader Georgia Gould told Sky News she had to act after fire safety fears were raised over four tower blocks in Camden, north London .
"We felt that something bad was happening and immediately rushed to the door, which was blocked by mud and rocks", he said. He said they struggled against the water until they met medical workers who took them to a hospital.
At a rescue headquarters' meeting Saturday night, Wang ordered around-the-clock monitoring of the geological conditions near the site to prevent secondary disasters, a prompt investigation, and appropriate care to relatives of the missing and those suffering losses in the disaster.
Experts on state media said the landslide was probably triggered by rain.
The local government said 142 tourists were recently in the area, which has some of the most spectacular mountain scenery in China, but had left before the disaster occurred. In May 2008, a magnitude 7.9 quake killed almost 90,000 people in Wenchuan county, some 40 kilometers (25 miles) away from Mao county.
Scientist He Siming told the state-run Beijing News that the 2008 quake could have done structural damage to the mountains flanking Xinmo.
It is reported that 62 households were buried and 120 people are missing.
A meteorologist interviewed by CCTV said there had been light rains in the area that would continue for a few days.
In 2014, a landslide in the same county killed 11 people when it struck a section of a highway.
