How many days are suitable for traveling to Hong Kong?

If you want to go shopping and go to attractions such as Ocean Park, Disneyland, Bauhinia Square and the Avenue of Stars, it will take 4 days. If you want to go shopping, it will take 5 days to cover most places in Hong Kong. If you add one more day, you can go to Macau, mainly to feel the atmosphere of the casino. If you don’t have this habit and interest, you don’t have to go. However, some things are cheaper in Hong Kong in Macau Pataca. So it takes 5-6 days which is good.
