visit to Hong Kong and then Macau from P.R of China.

Taimoor, you need to apply for two entry permits to HK and Macau separately. The first step is to prepare those materials including your passport and copy of its data page, the application form attached with a recently-taken bareheaded color photo, proof of your financial support, transportation arrangement such as flight itinerary and accommodation reservation, as well as your travel itinerary to the two places and your residence permit in PRC. You should prepare two applications and submit them separately to Beijing Office of the government of HK SAR and Beijing Office of the government of Macau SAR.
There is no requirement for the specific amount of your bank account, but you need to make sure that you have enough travel fees for the two places.
