You definitely have some positive elements in your profile for top 3 business programs in HK, such as a bachelor's degree from a well-respected Chinese university and work experience at both the internship and full-time levels. Your main challenges will be: (1) Explaining what your long-term, post-master's career goals are and how they connect to your pre-master's experience. It's a little confusing that you have both oil / gas sector and internet sector experience in your background, so you'll want to make sure that you have a clear explanation for why you worked in such different industries, as well as how all of those experiences will benefit you in your future career in your chosen sector. If you intend to switch sectors / industries, make sure you explain why a master's degree is a critical bridge for you. (2) Your academic credentials. Your GPA is on the lower side for a highly competitive business program, so your GMAT score will be an important way for you to demonstrate to admissions committees that you have the academic preparation for a master's degree.
