work permit canceled, but residence permit still valid, can i travel with it?

yes you can travel on it within mainland and also travel to Pakistan.

Thanks for reply, if I go to Hong Kong also I come back to china possible

It's really hard to say. Your boss can't cancel your resident permit. However, he can report your situation to local entry and exit management bureau. The bureau can cancel your resident permit without prior notice.

If you already quit, you should go to the bureau and try to change your resident permit to a temporary tourist type if you plan to stay. That's what you should do.

thanks dear
