Dear Sir/Madam

I am an Indonesian holding a Singapore student pass and planning to visit Macau,Hong Kong and China Mainland(Guangzhou). In my understanding Indonesian passport can get visa on arrival for Macau and Hong Kong, is that correct ? I also want to ask, now i have already hold the air ticket KL-Macau-KL, is that sufficient for the document needed ? since i am planning to visit Guangzhou by taking bus/train from Hongkong.

Thanks
