Is mainland chinas Visa is different with Macau?

Hi....my name is Reza .....Indonesian.... i have single entry china visa that i will use when I arrive in Ghuangzou.....before that i will visit Hong Kong and Macau. I am afraid if my single entry china visa will be used when i arrive in macau and i cannot go to guangzhou since the visa will be used in Macau. Is macau visa same with china? Thanks
