Xiong Yuxing, also known as Emma Xiong, was the first female grappler from China to be awarded a black belt in Brazilian jiu-jitsu, which she received from the hands of the legendary Letícia Ribeiro in June 2017. Xiong Yuxing is also one of the fastest recorded athletes to achieve the rank of black belt, having taken her just over 3 years to reach the grade, doing so after two sequential IBJJF world titles in the lower belt divisions.
