This will be her third time competing at the CGMO. She was a gold medalist last year.

The team of eight members will be sent to the international competition, which will be held Aug. 9–13 in Shijiazhuang, China, capital of Hebei Provence. Competitors will come from China, other East Asian countries including Russia, the United States, Canada, South Africa, United Kingdom, and Australia.
