Fu Qing, a third-rate university graduate, had worked hard in City S for five years and was finally promoted from clerk to supervisor. He didn't want to be taken over by a golden turtle who had returned from studying abroad. He was depressed and couldn't vent to others, so he bought a box of beer and went back to his cheap rental house to drink away his sorrow. He didn't expect to drink too much and fall asleep. He was back in his elementary school days. Seeing familiar and unfamiliar scenes around him, Fu Qing just wanted to pinch himself whether he was dreaming. Returning to Fu Qing in 1995, he discovered that a bronze mirror left to him by his grandma could connect to another world. Is this still the world he knew before? No matter, this time, he must live a promising life. But who can tell me that a single person who has been single for 29 years was caught in the mouth of someone who is really evil and pretends to be a loyal dog. Go away, bite me again, and let go.
