Description：Ying Ming (played by Zhao Yi), a swimming pool lifeguard who can't swim, was fired after being exposed. His creditors sent thugs to block him on the street. Fortunately, his girlfriend Xiao Ke (played by Li Nian), a saleswoman, never left him. Ying Ming lied to his girlfriend that he was a doctor, and borrowed a friend's house in his busy schedule to report to his future mother-in-law. His mother-in-law was dissatisfied with the wedding house, so Ying Ming pretended to sell his friend's house and borrowed the same house to promise Xiao Ke a happy life in the future. Taking advantage of Xiao Ke's nitpicking, Ying Ming once again sold the house that someone else had entrusted him to sell. After a while, Ying Ming discovered the profit of acting as an agent for house sales, and also saw through the house sales talent hidden in himself, so he embarked on the journey of house sales with the unemployed Xiao Ke. Ying Ming used all his tricks to deal with multiple defective houses, but he was tricked by a master in the field. He was unwilling to fail.
