What should I prepare for a trip to Prague?

Take a folding umbrella, it's easy to rain, and it's cold. You'd better take a coat. Be careful of the exchanges all over the street. Many informal shops are black shops, earning more than 25% of transaction fees, and regardless of the police, they have to go to regular banks and exchange points, and the exchange rate is relatively high. It's best to confirm with the clerk how much you can change before changing it, otherwise once you change it, you can't change it. Choosing AAA as a taxi will not deceive tourists. Many private taxis charge too much, and if they feel wrong, they ask to get off at once. In addition, you should know what fare to buy by subway. It is recommended to buy a 24-hour ticket for 100 kronor, or transfer to any indoor bus. You can print the time when you use it for the first time, and you only need to print it once. If you buy the wrong fare, you will be fined 700 kronor if you are found by plainclothes. Consumption is not high, and eating is generally 200-300 kronor per capita. Four-star hotels outside the old city are around 600 yuan for one night. It is easy to get lost in the old city, so you need a map to ask for directions. It is recommended to visit Prague by subway, tram and walk.
