I am British, and I live in China with my Chinese husband.

I want to stay in China, but do I have to continue working to stay? What about when I reach retirement age? If I cannot stay in China with a work visa, then how else can I stay in China with my husband? We have known each other for 10 years, and have been married for 3 years. I am reluctant to change my citizenship, as I still need to get back to England to visit family and friends. Is this my only option, to change my citizenship?
