I watched the whole match. Julia has really, REALLY big weapons, but is much too inconsistent. She had better shots than Zhang, but didn't get enough balls in the court to make it a close match. Misses way too much. And she is a total hothead. Gets really mad at herself when she misses an easy shot (which happens somewhat often). If she can get more level-headed and can make more shots, she will be top 50, period. But until then, she will struggle to stay even in the top 100.
Sadly, if you go back several years on this thread, you will finds comments similar to yours over and over again.
