Other proposals under consideration include giving priority to local people on the housing list and having tighter rules on people not paying their rent.
The military has issued stricter spending rules to curb waste and extravagance and calls for priority spending on preparations for battle, high-tech weaponry and training, according to Xinhua.
Now the United Network for Organ Sharing is considering changing the rules for kidneys to be more like hearts, matching younger donors with younger recipients and also giving priority to the healthier patients.
