When a patient died in ancient China what was hung outside the doctor's house?

Son of The Household Cavalry

In ancient China doctors were paid when their patients were kept well, not when they were sick. Believing that it was the doctor's job to prevent disease, Chinese doctors often paid the patient if the patient lost his health. Further, if a patient died, a special lantern was hung outside the doctor's house. At each death another lantern was added. Too many of these lanterns were certain to ensure a slow trade. http://www.telacommunications.com/misc/facts.htm Mar 26 02, 7:46 AM
