Intern salary in Hong Kong?

Hi there everyone, I am hoping to get some info about a series of issues related to moving and living in Hong Kong. I am considering moving there for an internship. My questions are the following: 1. Is a HK 13000 salary ok for an internship? It would be at a higher education institution that provides accommodation as well. 2. I have read the posts about the high costs in Hong Kong and about the implicit difficulties of putting money aside. I am just wondering if the abovementioned salary could allow me to save up, if the accommodation is already payed for by the employer. I don't have an extravagant lifestyle, nor am I extremely adventurous, so I would like to know ( from your experience ) if Hong Kong is really not the best choice when it comes to saving up. 3. Is it legal to possibly have a minijob alongside the internship (such as tutoring, or doing freelance translations)? 4. I understood that the expat community is friendly, but what about the locals' attitude towards foreigners? I ask because during my brief time in a smaller Chinese city I was being stared at, and it's not someting I enjoyed very much. :) Thank you in advance for your answers. Any help is greatly appreciated!
