Because there is a European railway pass, there is a free train to go to Berlin. The white clouds in the suburbs go to Berlin for a cloudy day. After the trip, the bicycles are rented and started to wander. Berlin is not as beautiful as it is, and the taste of the whole city is not very good. The smell of the tail is very heavy. Today it happened that all the police in the vicinity of the Berlin Cathedral were closed, and the traffic lights in the downtown area all went on strike. The whole traffic became chaotic, and police cars were on duty at each intersection.
