Chinese tourist Visa in Macau

Hi Sirs,
I am a Filipino citizen but living in California, USA. I went to Shanghai from California, and stayed their for 4 months in tourist visa (2-MONTH + 2 Months extension=4 months). I exited in Hong Kong, then went to Macau for holiday. I am now in Macau in tourist visa. Would that be possible to apply and obtained a Chinese tourist visa while in Macau? I have a "sufficient funds (to show), invitation letter from a friend, and a confirmed air ticket" going back to California, USA. Please advice. ASAP

Thanks,
Willy
