Another landslide at 6:30 am in Mumianwan community, Longgang district, damaged four residential buildings, housing 75 people. Sixty-one people managed to escape and 10 were rescued. One of those rescued died on the way to hospital. Rescuers are still searching for the rest four missing.

Tropical storm Fengshen made landfall at Shenzhen early on Wednesday, bringing heavy rains. Rainfall in the city during past five days has reached a record 1,300 millimeters.

A 19-year-old migrant worker surnamed Jia, from Nanchong in Sichuan Province, was reported earlier Sunday to have been killed after falling into the sluice channel of a swollen reservoir in Shenzhen.
