Grandpa said that as a yin-yang master, you have to fight not only ghosts, but people too. I didn't understand at first. It was only after I entered the trade that I learned the truth: rival practitioners stealing my business, troublesome evil spirits, strange clients, and terrifying zombies. I took over Grandpa's run-down incense shop, and now I have to deal with all kinds of bizarre jobs while trying to survive among a crowd of established old businesses.
