This study provides an in-depth analysis of the trajectory of China's junior tennis CTJ (China Tennis Junior) tournaments between 2022 and 2023 and examines the impact of these changes on junior tennis in China. With the support of government policies, the improvement of the socioeconomic environment, and the focus on sports in family education, the number of CTJ tournaments jumped from 70 in 2022 to 568 in 2023, and the number of participants also increased significantly. By applying descriptive statistical analysis and trend analysis methods, we reveal the changes in tournaments in terms of level settings, gender ratios, and participation by age groups. The findings suggest that the increase in the number of high-level tournaments has provided a broader competitive platform for outstanding players, while the wide participation of the U10 and U12 age groups highlights the importance of early education in tennis. Based on these findings, this paper suggests that tennis development should be promoted by expanding the coverage of tournaments, optimizing tournament structure, and further strengthening early physical education. These findings not only provide data support for the current state of youth tennis in China but also provide valuable references for future policy making.
