A 91-year-old man diagnosed by mainland doctors as suffering from pneumonia was rushed back to Hong Kong for treatment last night. Ho Ching, who had been coughing badly for four days, was admitted to Northern Hospital in stable condition. Mr Ho had spent the Lunar New Year with his children in Hong Kong before returning to Zhangmutou, a small town north of Shenzhen, which he uses as a second home. His daughter said doctors at a hospital in Zhangmutou diagnosed her father as suffering from pneumonia and required him to be hospitalised at a cost of $2,000 a day. With the help of a friend, Mr Ho was driven to Huanggang, where a report was made to the Hong Kong police. Ambulancemen wore face masks when taking Mr Ho to the hospital. His daughter also had to wear a mask.
