Doctor Yang of Shanxi was a master of acupuncture, capable of commanding spirits to serve his will.

Every time he ventured out, the ones leading his horse and holding the whip were ghosts from the netherworld.

One evening, Doctor Yang was returning home with a friend when they encountered two men midway—tall figures with grotesque faces, clearly not living men.

His friend was greatly terrified.

Doctor Yang inquired, "Who are you two?" They replied, "King Long-Leg and Li the Big-Head, dispatched to escort our master." Doctor Yang commanded, "Lead the way." The two turned and moved off with surprising speed.

Whenever Master Yang slowed his pace, they would halt and wait, their demeanor utterly respectful, just like devoted slaves.
