I'm here at macao now working. and my boss want me to get china visa. it possible and how ?

It is possible. If you go to PRC for business purpose, you need to apply for a business M type entry permit. You should first prepare the required documents including your passport and copy of its data page, a completed application form attached with a passport-style photo, an invitation letter from a business partner in mainland PRC, as well as your residence permit in Macau.
Next, submit the application to the office of the commissioner of the ministry of foreign affairs of PRC in Macau SAR to apply for the M type entry permit.
