I definitely recommend you to go to Guilin University of Technology. The admission to Guilin University of Technology is 50/50 in culture, your major is the first, and you can get 300 in culture, which is still very secure for your total score.
If you apply for Yi Yun, your major ranking is not high, and you didn't get 350 points in the culture class. Look before you leap, don't be impulsive.
