Need your help been searching for answer since lastweek.

Im invited to work for short time in shenzhen 3 months with multiple entry, but the company is based in HK and they will base me in sz. Btw im from the philippines, the company based in HK gave me a company invitation letter. Can the company invitation letter from HK support my application? Im fresh graduate from a university, can my parents sponsor me on business F? will shoulder all my expenses like airfare and accomodation.

Hope you can help,
Thank you,
