I didn't exchange a single Hong Kong dollar, but still had a blast in Hong Kong for a day.

Before going to Hong Kong, I was really worried about whether I needed to exchange Hong Kong dollars. I checked various travel guides, and everyone seemed to have different opinions. After a 20-hour layover, I can confirm from personal experience that there's no need to exchange Hong Kong dollars. 🗺️A few tips: Regarding transit passengers entering Hong Kong: After arriving at Hong Kong Airport, take the train to checkpoint E2 and enter the visitor channel. Starting from October 2024, you no longer need to fill out an arrival application form. You can directly go through the process with your connecting flight ticket. 🚌Getting from the airport to the city center: You can choose between the Airport Express and the bus. I chose the Airport Express, which took about 30 minutes. Two-person and three-person tickets are cheaper than single tickets. You can buy tickets directly from the vending machines using WeChat or Alipay, which is very convenient. 🚇Taking the subway: There's no need to buy an Octopus card. You can simply search for "public transport card" on WeChat or Alipay and activate it. It's basically the same as in Chongqing, with automatic exchange rate conversion. 🚶City walk route: I didn't follow any of the routes I had planned. I took the Airport Express directly to Hong Kong Station and walked from Central to Kennedy Town. Along the way, I visited Health Street, the former Gunpowder Magazine, the University of Hong Kong, Winstons Coffee, and % Arabica. The entire journey didn't feel particularly long, but the uphill and downhill stretches were quite tiring. Regarding food and beverage expenses: For two people staying for 20 hours, including round-trip Airport Express tickets, lunch, and dinner, we spent a whopping 1,000 RMB, and we didn't buy anything. We walked everywhere. We had lunch at a *cha chaan teng* (tea restaurant) and dinner (pasta + small burger + two beers). The prices were exorbitant.
