If you don't mind, it would be best to post the generic parts of the contract if case it's necessary to exclude any proprietary or sensitive info, which is unlikely.
I don't know much about Zhuhai, but I live in nearby Guangzhou. You are close to Macau and Hong Kong, which is a nice to have for most people, but not a super-fantastic, except for the convenience of the HK airport.
Guangdong is rapidly and massively expanding their public transportation system, mostly trains, so that it will be convenient to travel around the central and southeast and east part of Guangdong. It's probably the biggest public transportation project in the history of the world.
I've never heard anything bad about Zhuhai and not a lot of neutral. People seem to like it for a relatively not-huge city that has a reputation for being very clean and organized. If you like sea food and ocean swimming, those are bonuses. If you speak Portugese and Cantonese, those are bonuses.
