Partner travel

Hi Guys.
Hope you can advise. I will be working in China for a hotel chain and I am currently going through the visa application process. My girlfriend of three years will also be joining me but since we are not married she will be applying on a seperate application. I will be fully supporting her during our stay in China. I am of British nationality, my partner Malaysian. Ideally my partner would have a year long multi entry visa, or multi entry 3 month which could be extended or renewd, any tips or advice as to how to go about this.
