Why does Binzhou hold martial arts routines and judo?

Generally, each city is allowed to declare and host its own advantageous projects. Because there is a world champion in martial arts in Binzhou - Cao Jing; and in judo Binzhou has a pair of sisters - Xu Yuhua. Xu Lili is on the national team, has also won a medal at a certain level in the World Championships, and participated in the Beijing Olympics. Therefore, through the efforts of the Binzhou Municipal Government and the Sports Bureau, Binzhou undertook the above two projects.
