In the morning, from the town of CK, to go to Karlovy Vary, first pass the town of Budweiser, the tour guide arranged for us to stop and visit, and eat in Budweiser at noon. I don't know if it is because of the off-season in winter or this day is a Sunday relationship. There are no people in the town. I wanted to change the Czech krona here and didn't open the door. Seeing an underground supermarket, go in and go shopping, all kinds of chocolates are super cheap, the imported food usually bought, the price here is too attractive. The focus is still to go to the town's famous Pushmisl • Otkar II Square, which is said to be the largest square in the Czech Republic. The square is square, surrounded by various European buildings, Baroque, Gothic, Renaissance, colorful colors, very beautiful. The most striking is the town hall with a bell tower, many flags are inserted on the outside wall, and various badges are engraved, which is really beautiful. On the other side, there is a towering black building called the black tower, which is very conspicuous. Because the square is under construction, it hinders the view, and it is impossible to watch and photograph the entire square in a complete way, and it is impossible to sit quietly on the square and feel it. It seems that winter is really unwise to come to Europe, and has encountered several repairs and construction.
