Let me explain the bad points first. If you have any mobility problem, phobia's, asthma or "LUNG DISEASE" do not go.The stairs are in character with the Museum. The oldest surviving "OPERATING THEATRE IN EUROPE THAT WAS BUILT IN 1822."
Once inside it becomes full of surgicaL objects and herbs.The herbs are are not exiting too look at. However, they are being used by the chinese as a medication now. You have to see the old operating table, knives, saws and "dentist equipment"! as well as a genuine sceleton.
