I have tickets to Macau to arrive Aug 5, 2011 and back to Philippines Aug 10, 2011. I will get a Chinese visa beforehand and try to enter mainland China via Macau ports. I want to spend a day in Macau and then try to get to Yunnan Province, then back to Macau in time for my flight back. In your opinion, is this doable, or do I have too little time?
