Hi Shiqing.
Very well written. I can hardly find any grammar mistakes. I just want to give you some advice on the content.
The part you describe your academic background is absolutely great, but the part you describe your professional background is too general.
My communication with leaders, colleagues and clients has taught me the importance of interpersonal skills and practical ability which one could only develop by continuously applying knowledge into practice.
Is that it? Have you witness something that you read about on some books? Did you meet any differences between real life work and textbooks?
Also, you can be more specific when talking about how USC fits you. For example the following sentence:
With an outstanding team of professors, students, practitioners and film industry leaders, University of Southern California is the ideal place for me to start working my way up and establishing useful connections with experienced professionals who can set me on the right road to my career goals.
What lessons exactly? Which professor? You can find more details online.
