Q:Read the following article and select the best answer. Article: Doctors' moonlighting is becoming popular in hospitals around China. It has not only raised a lot of heated discussions in the media, but also caught the attention of the central government in Beijing. On December 26, a spokesman of the Ministry of Health stressed that the ministry was firmly against doctors' moonlighting, while strict regulations should be applied to doctors taking part-time jobs, the Xinhua News Agency reported. Last year, the Ministry sent out a notice to a variety of health organizations to speed up the reform of their personnel system. According to the notice, medical organizations can hire medical experts as part-time doctors but such activities should take place under the hospital's management and regulations . As for moonlighting--meaning that the doctor provides medical service without the permission of the original hospital--such activity goes against China's Practicing Doctor Law, Xinhua reported. In China, doctors used to be controlled by hospitals and they could work for only one hospital. However, as China's medical personnel system reform developed, it has been recognized that medical human resources, just like human resources in other areas, should be shared by the whole society. But on the other hand, doctors' taking part-time jobs should follow the relative regulations applied in the medical field. First of all, they should follow relative government laws and regulations. They should also follow the rules and regulations set by the medical organizations they work for. In addition, they should pay taxes for their income from the part-time jobs. What matters most is that they should first finish their regular jobs as required and be responsible for patients to ensure qualified and safe medical treatment.
