Ali for Q1 Visa for my wife

Dear,

I'm working in China and I have Work Z for one year. I get married last week and I need to apply a permit for my wife. Do I need to go to my country and apply it from there ? or I can ask Police station to give me a letter and my wife goes to Embassy to apply hers to enter to China ? How many days takes to have it for her?
Thanks in advance for your answer.
