Traveling to South Germany, there is a famous tour route, which is the road to fairy tales. Rothenburg on the high hills on the eastern bank of the Tauber River, a tributary to the south of the Rhine, is the jewel of this road. Most towns in Germany have been baptized by war. Rothenburg is no exception. The strong Rothenburg people used a watt and a stone to completely rebuild the town as it was, a nirvana. Through the gates of the castle, every lane here leads to the market square, looking at the window sills filled with flowers, the blue stone road, the slow carriage, and the towers and church spires that you can see at random. People feel that time has reversed and they have stunned their youth.
