The Wandering Medical Saint

The wandering village doctor has lost his memories. People call him Ersha. Ersha has three rules: no treatment without money, no treatment when he's not in the mood, and no treatment if there's nothing wrong with you! But money is never a problem. Treatments start at three yuan, and for a hundred or so, he'll cure just about anything! As for his mood, as long as Shi Zhai doesn't annoy him too much, he doesn't really care. Nothing wrong with you? That's impossible! The fresh graduate who just came home to the village doesn't look too well. Must be a yin-yang imbalance; she needs a little adjustment. Old Wang's family down the mountain? Too much internal heat. He needs some care. And those vacant eyes over on the western hill? They look like the illness is already terminal. Better give him emergency treatment...
