As for how much you spend, it depends on how you spend it. It can be cheap or valuable. However, generally, the hotel expenses, transportation and catering for two days after going to Hong Kong cost 4,000 yuan according to the cheapest two people, and the expensive ones cost tens of thousands to hundreds of thousands.

Apart from the uncertain shopping expenses, the biggest expense may be the hotel. If you stay in a hotel near Tsim Sha Tsui, Mong Kok, shopping is convenient, with more than 800 three-star hotels. It's much cheaper to live in the New Territories, but it's also a problem to spend 1 hour going downtown by bus every day. If you know the bus route, you can choose Jiahu Hotel in the New Territories, which is very good. It's a four-star hotel with a room of 25 square meters (there are too few hotels with such a large area in Hong Kong), and convenient shopping spots such as Wanning, Watsons and Wellcome nearby are also very convenient. There is a direct bus from 50 yuan dollars to Tsim Sha Tsui in front of the hotel. Hong Kong's transportation cost is very expensive, so it's good for one person to calculate the transportation cost for three days at least in 200 yuan. As for the rest, catering can be cheap or valuable, depending on how you choose! However, even if you go to an ordinary tea restaurant in Hong Kong, it will cost more than 50 yuan for two people to eat. If it is near Mong Kok, it is more than 80 yuan (fast food+drinks). 45 yuan tasted a bowl of wonton (chaos) in a small restaurant, but everyone had to queue up. There are five small wonton in the soup bowl, hehe! Even if you find a porridge shop with a roadside stall, you can have 20 yuan for a bowl of porridge, but it tastes good.
