I Have a Date with Zombie Yin and Yang

The male protagonist Chen Yin-yang is the middle man between zombies and humans, and the female protagonist Ma Linglong is a descendant of the Ma family of the dragon clan who exorcises demons. Chen Yin Yang was born in an old tenement house in Sham Shui Po. His grandfather was a fortune teller who traveled around the streets and had been reading Feng Shui for decades, half truthfully and half falsely. His parents died in a car accident when he was three years old, and his grandfather raised him single-handedly. He has been taught since childhood that "you have a special destiny, at the intersection of yin and yang", but he only thinks of it as an old man's god. Grandpa passed away two years ago, leaving him with a second-hand bookstore heavily in debt and a cabinet of incomprehensible ancient books. He barely made a living by selling second-hand comics and novels. He often dreamed of a well at night, but he didn't take it too seriously - until the night of the first blood moon, when zombies wearing Qing Dynasty official uniforms blocked his path.
