Is This Really a Ghost?

Ghosts really exist in the world, but they only separate the yin and yang worlds. People are exposed in yang, while ghosts hide in yin. Therefore, ghosts can see people, but people cannot see ghosts. However, there is a kind of people who are born no different from ordinary people, but they can contact ghosts, walk between the yin and yang worlds, and send the ghosts who remain in the world into reincarnation to reincarnate.
