A SURVIVOR of the Tsuen Wan landslide which hit a minibus, said it was a miracle that only one person was killed. Speaking from the observation room at Tuen Mun Hospital, Cliff Lau King-fu, a 32-year-old marketing manager for a European electronics firm, said: ''It was terrible. The mud hit us so fast that we did not know what was happening at first. ''I was completely covered in the dirt and rock. It really is a miracle that nobody else was badly hurt.'' Mr Lau, whose wife is five months pregnant, said he had thought he was going to die when he saw the mud heading for the minibus. ''I was looking out the window when I saw stones and sand sliding towards us. The next thing I remember is being totally covered in the sand. I couldn't breathe and I thought I was going to die. ''But then two guys who were helping to get people out uncovered me and took me out too,'' he said. Mr Lau said he was buried for about two minutes and that he was just one of a few who were covered in the wet sand. Most were tossed about the bus, but managed to walk away. Mr Lau checked out of Tuen Mun Hospital with scrapes and bruised ribs shortly after 6 pm.
