Is it expensive to travel from Chengdu to Hong Kong and Macao for half a month?

The round-trip ticket is 2000 yuan per person, and my place is more expensive. At that time, my stay in Hong Kong was 4 nights less than that in 3K, and the places in Kowloon and Macau were similar. Of course, there are some cheap ones, 1 at least 200 yuan per night, which may not be as good as the guest houses in the mainland, and the food is more expensive, so 100 yuan per person per day. Transportation costs, MTR generally a few dollars to a dozen dollars, the rental price is similar to Shanghai, and the bus costs a few dollars. It's just estimated that each person is more than ten yuan per day. There is no subway in Macao, so you can take the bus. How to calculate it depends on your itinerary. It seems that the average pass stays in Hong Kong and Macao for no more than 7 days.
