GUANGZHOU, Dec. 23 (Xinhua) -- Doctors who take day shifts at work may find use for their medical expertise in the "night clinic", which opened on Saturday by a doctors-sharing platform in south China city of Guangzhou.

"Top Doctor Center" was established in Guangzhou by a Hongkang Doctors Group, a private company. It has signed contracts with 500 doctors, who hold assistant professor level or higher credentials for their service.

The center is located at a building which was used for the Canton Fair. Total floor space is around 20,000 square meters. It has 146 rooms and five surgery centers. Total investment for the first phase is 200 million yuan (more thann 30 million U.S. dollars) and it can accommodate 4,000 patients a day, said Zhan Zhiyong, founder of the platform.

The night clinic lasts from six to nine in the night. The clinics are also open during the afternoon, when doctors can come to work in their off-hours.

Song Donglei, a doctor specialized in cerebral surgery, is one of the contracted experts. "Shared doctors have become reality. Platforms like this are growing larger in size, with strong facilities and modern management ideas," he said.

"By providing diverse medical service, shared doctors may be the future of medical service in China," he said.
