i am travelling to Macau- do i need HK visa as we if want to travel HK

Ali, you need to apply for two separate entry permits to visit Macau and HK.
You should firs prepare the required materials including copy of your passport, the completed application form, a passport-style photo, proof of your financial support, hotel reservation, transportation arrangement, and your travel itinerary.
After, make two applications and then submit them to the embassy of PRC to apply for the entry permits.
