From August 10 to 15, 2026, the 25th Chinese Girls' Mathematical Olympiad (CGMO) was held at the High School Affiliated to Hunan Normal University. The competition brought together more than 230 outstanding female competitors from 39 delegations representing provinces, autonomous regions, and municipalities across China, as well as Hong Kong, Macao, and Singapore. Beijing's female delegation this year comprised 7 members, 4 of whom were RDFZ students, with RDFZ teacher Zhang Yumeng serving as team leader.
After two days of intense competition, RDFZ's four participants — Wen Jiahui, Lou Huaijin, Li Yitong, and Liu Pinmo — lived up to expectations, all winning gold medals and placing among the top 22 nationally. They qualified for the 2026 Chinese Mathematical Olympiad (CMO) Winter Camp. The number of RDFZ students advancing to the CMO Winter Camp ranked first in the nation, setting a new school record for the highest number of students advancing to the CMO Winter Camp in a single CGMO competition.

Among the four team members, Lou Huaijin is a rising Grade 11 student at RDFZ, coached by Teacher Song Kun. Wen Jiahui, Liu Pinmo, and Li Yitong are all rising Grade 10 students, with Teacher Tang Xiaoxu serving as both their competition coach and junior high homeroom teacher. The head coach of mathematics competitions at RDFZ is Teacher Tang Xiaomiao.
Appendix: About the Chinese Girls' Mathematical Olympiad (CGMO)
The Chinese Girls' Mathematical Olympiad (CGMO) is organized by the Chinese Mathematical Society. It is a national high-level mathematics competition designed exclusively for female secondary school students in China. Since its inaugural edition in 2002, the competition has spanned 25 years. The competition aims to build a dedicated platform, encouraging more girls to explore the beauty of mathematics and deepen their study of foundational disciplines, breaking down entrenched biases in mathematics and science education, and identifying and cultivating outstanding female mathematics talent for the future. Over the years, it has attracted delegations from provinces, municipalities, and regions across China, including Hong Kong, Macao, Taiwan, and overseas, and has grown into a youth women's mathematics event with international influence. The competition follows a two-day written examination format, with four problems set each day covering the four core competition areas of algebra, geometry, number theory, and combinatorics, comprehensively assessing participants' logical reasoning, constructive argumentation, and overall problem-solving abilities. Top gold medalists are directly awarded qualification for the Chinese Mathematical Olympiad (CMO) Winter Camp, making it one of the important selection channels for top mathematical talent in China.
