"Yin Yang Delivery Guy" tells the story of customer service Li Na's extraordinary job - she can understand the language of spirits and connects the yin and yang worlds through the delivery system. When customers complain about "unusual food", it is actually evil spirits; the so-called "wrong address" is actually the entrance to the spirit world. Through keystrokes and late-night trips, she untied the entanglement between the two worlds and delivered salvation.
