SHANGHAI, Aug. 7 (Xinhuanet) -- China's largest city, Shanghai, is still fighting against the aftermath of typhoon Matsa that left Shanghai in the wee hours of Sunday, as the city is yet to resume normal air and water traffic operation.

    The city's two international airports, Hongqiao and Pudong, reopened at around 8:00 a.m. Sunday, but it is still difficult to maintain normal operation because of the huge number of flights laid over by the stormy weather since Friday night.

    The two airports together had less than 20 takeoffs and landings in the past 40 hours, compared with usual 1,000 flights per day.

    As the weather report says rainstorm will hit Shanghai again Sunday night, civil aviation authorities say the two airports will not restore normal operation until Monday.

    Shanghai's water traffic resumed at Chongming, Hengsha and Changxing islands at 11:00 a.m., but the scheduled ferry services to Daishan, Putuo and Dinghai will not resume until Monday night.

    In the small hours of Sunday, maritime rescuers in Shanghai saved four sailors from two barges that were damaged by the typhoon in water off Shanghai. The wind speed was 26 meters per second at the time, according to sources with the Shanghai Salvage Bureau under the Ministry of Communications.

    Torrential rain brought about by the ninth typhoon of the year also flooded many urban streets and residential buildings in Shanghai Saturday night and Sunday morning.

    The No. 1 subway line, a trunk underground route, was drowned at a section between Changshu and Xujiahui stations in the city center at 5:00 a.m. when rainwater poured into the underground tunnel.

    That section of the subway line was suspended operation for five hours and thousands of passengers had to turn to buses or taxies. Enditem
