I think the American girl messed up Koreans

I am sure Koreans had plan A, B, C before the 1500mm final, but their plan didn't include the American girl.

The American girl, as you guys call her "Jiao Shi Gun" suddenly came to the show, and Korean girls had no plan for her. Then Zhou Yang broke out, and when Korean girls realized that, it was too late. They were already far behind, there was nothing they could do.
