CHENGDU, Sept. 5 (Xinhua) -- About 9,000 passengers were stranded Wednesday due to heavy rain in Chengdu, capital of southwest China's Sichuan Province, according to local authorities.

A rainstorm hit the city from 3 a.m. to 5 a.m. Wednesday. Starting from 10:30 a.m., heavy rain again pelted through the city, forcing the airport to temporarily close both of its runways twice.
