Billionaire (Chinese: 西虹市首富; pinyin: Xī Hóng Shì Shǒu Fù) is a 2018 comedy film written and directed by Yan Fei and Peng Damo, starring Shen Teng, Song Yunhua, Zhang Yiming, Chang Yuan, Zhang Chenguang, Wei Xiang, etc.

He rented an entire hotel for a month at a price of ¥20 million, invested in sunset industries and unfulfilled dreams, and funded the production of a land-swimming machine, hoping that this would help him lose money.

He also spent ¥10 million to invite Changzhou Hengtai, the top soccer team in the country, for a friendly match against Daxiang.

After the match, Wang Duoyu found that Xia Zhu had been abducted, and would die if he did not arrive and pay ¥10 million before 6 PM that day.

Since this would violate the rules, Wang Duoyu hesitated for a while, but he ultimately decided to go and pay the money to rescue Xia Zhu.

At the end of the film, Wang Duoyu and Xia Zhu got married and wanted to donate their 30 billion yuan to charity, but asked to keep all the money needed to raise a child, which turned out to be a massive amount that they couldn't work out well into the night.
