Originally, the Cologne Carnival was best written in the old market square, but only found the city hall on the old market square, write here. The old market square and the city hall are the main venues for the opening ceremony of the Cologne Carnival. The largest carnival in Germany, opened at 11:11 on November 11th on time in the old market square, has entered the "fifth season" from this moment, the original cold and gloomy winter in this lively environment that lasts until the end of February the next year seems to be difficult to find its own trace. The origin of the Germanic carnival is indeed a celebration of the winter solstice, to revel in the drive away of the evil winter devil. I was fortunate to participate in an opening, and equipped with a selfie artifact, I successfully captured some images of happy people. Every time I look again, I am still happy and will not smell the urine smell in the streets and alleys when I am on the scene. Everyone's tavern, street beer are not far from drinking, How can the public toilets be queued... Unfortunately, my face is not smeared, obviously watching the excitement. Cologne Carnival is a climax and featured in the February women's carnival tie, but unfortunately I was not able to see it.
