Tennis, compared to other sports, is considered a relatively niche athletic activity. Many viewers became interested in the sport only after the emergence of Chinese player Li Na. After Li Na's retirement, the sport was once again relegated to obscurity by audiences. It wasn't until recent years that a group of outstanding Chinese tennis athletes appeared, causing the sport to regain public attention. The primary contributor to this phenomenon is none other than tennis queen Zheng Qinwen. Zheng Qinwen's peak moment was undoubtedly winning the Olympic women's singles championship, which also made her China's first-ever Olympic women's singles champion. The value of this gold medal speaks for itself. Not only did it introduce more people to Zheng Qinwen, but it also elevated her sporting career to new heights, achieving both fame and fortune. As we all know, the income sources for athletes extend beyond competition winnings; brand endorsements constitute the bulk of their earnings.
