Footage from the scene showed downed trees and rubble piled up along muddy roads, with rescue teams of nearly 1,000 people with dogs looking for those missing.
At least 21 people are now confirmed to have died and six others are missing in China following a mudslide triggered by heavy rains.
Houses were destroyed, power was cut to 900 homes, and a highway was damaged following the mudslide and flash flooding on the edge of the northwestern city of Xian on Friday, said authorities.
Footage from the scene showed downed trees and rubble piled up along muddy roads in a village, as the country grapples with unusually high summer rainfall.
Rescue teams, comprising nearly 1,000 people with dogs, were looking for the remaining missing.
In the southwest of the country, around 81,000 people were evacuated from high-risk areas of the Sichuan province. Heavy rain caused hillsides to collapse and disrupted traffic, but there was no news about deaths or injuries.
In the northeast, Typhoon Khanun, which had earlier pummelled Japan, weakened into a tropical depression when it made landfall in Liaoning province on Friday night.
But its rains still led to flooding fears for low-lying cities including Anshan, where nearly 18,000 people had been evacuated.
More than 20 trains were cancelled in Shenyang, the biggest city in the northeast, and surrounding Liaoning province.
Also in the northeast, six rivers and reservoirs in Heilongjiang province were above warning levels.
Parts of China suffer heavy rains and flooding every summer, but this year has been unusually severe in some areas, while other regions struggle with drought that is damaging crops.
Across the country, a total of 142 people were killed by flooding, landslides and mountain torrents in July, according to officials.
