Introduction: Aman, a rich boy from Hong Kong, traveled to the mainland alone and accidentally lost his clothes. Even the hotel luggage was taken away. Unable to enter the hotel, Oman had to wander around. Just when he was helpless, Cai Yun, a sister from Sichuan, came to him, helped him find a temporary job and took care of his life. In sincere contact and communication, the two fell in love. Aman worked hard at the construction site and tried to contact his family after earning money. Oman's father came to the construction site to look for his missing son. In a blink of an eye, Aman changed from a temporary worker to a young man. Cai Yun turned and left, and Aman caught up: "I am not a Hong Kong man!"
