Asking about getting visa to China from hong kong or Macau?

Dear China aplication center

I am Samer Ibrahim AL Sawalhi.from Jordan

I came to Shanghai for the first time for training at a hospital for one year, but the China Embassy at Jordan gave me one Month(category F).

I would ask if I can do exit to Hong Kong and if it feasible to apply for another visa.?

How many days it will take???
Thanks
