Yixintang in Shuishui Town is a medicine hall. It is said that it existed when Qingshui Town was still a dilapidated small village. The head of Yixintang is a woman, about seventeen or eighteen years old, with a very ordinary appearance. She wears white washed gray clothes and a light green hairpin. She is always lazy. Yixintang has a doctor, a waiter and an old woman who cooks. Doctor Yin is a well-known miracle doctor. The errand boy is a young man of fourteen or fifteen years old with a very bad temper. The old woman who cooks is mute, so people call her Mute Mom. One morning after a rainy night, Yishintang welcomed a special patient. The patient was a very beautiful woman. When he opened the door, Koizumi looked straight. He had never seen such a beautiful woman, lying in a gorgeous carriage, dying.
