Wang Duoyu, male, is the richest man in the movie Xihong City. Played by China actor Shen Teng, when his life was at a low ebb, he learned that his second grandfather, who had run away from home in those years, had become a rich man in Taiwan Province province. Because he has no children, he is ready to inherit his property of more than 30 billion yuan, but the premise is that he can spend it all in one month, but there are a series of restrictions such as not buying a car, buying a house, giving it away, which makes him feel "particularly worried about spending money" for the first time, which has triggered a series of hilarious stories.
