I m currently working in China, I m having F visa n I want to convert it in to Z, Procedure pls?

You can't convert your China F visa to Z visa in fact. What you should do is to apply for a new Z visa, then your F visa will expire automatically on the issuing of your new Z visa. Meanwhile, it's hard for you to get a Z visa without exiting China, you have to go to Hk to have a try even if you won't want to go back to India. You are advised to go to the local public security bureau to enquire about this.
