Wang Xiaoli, a member of the China Badminton Team, currently ranks first in the women's doubles world and is the champion of women's doubles in the 201kloc-0/badminton world championships. On September 20 10, it officially appeared as a new combination of Guoyu. By the end of February, it was only half a year since Wang Xiaoli and Yu Yang won five individual champions, 1 team champion and 1 individual runner-up in the seven competitions they participated in together. This not only made the coaches see the effect of painful demolition on the formation of a strong alliance, but also increased the confidence of the two sisters in fighting side by side in London.
