How can I obtain a family reunion resident permit for up to 5 years.

If my wife (Overseas Chinese) entered Guangdong Province (Dongguan City) with a Family Reunion Q1 visa to visiting me (I am Hong Kong permanently resident with an China entry-exit pass and living in China). How can I apply for her temporary resident permit base on her Q1 condition? Do I need to travel to the Guangdong Province, entry-exit security bureau admin in Guangzhou to submit application or can do it in my local area police station in Zhangmutou Town?
