Qian Guang is a tenant renting the front-facing rooms of the Lu family residence. He works as a clerk at the prefectural office and is described as thin and short, always wearing a smile, making him appear particularly amiable and smooth in his dealings. He lives with his wife and daughter Jin Niang as a family of three, having rented the Lu family's rooms many years earlier when the family had little income. He is perceptive and understands social niceties, not overstepping his boundaries when interacting with Lu Runrun. He left early and returned late every day, and out of propriety, rarely had contact with Lu Runrun's family.
