Early in the morning of May 1, we said goodbye to Heidelberg and drove three hours to Munich, a key town in southern Germany. It was a sunny afternoon. We were walking on the street with flowers blooming. From St. Michael's Church, Notre Dame Church, to the New Town Hall and Maria Square, we passed together. It might be the reason for Saturday. Maria Square was very busy. There happened to be sponsorship activities by non-governmental organizations. Everyone could enjoy a cup of coffee and cake, and a bunch of beer and coincidence in the open-air bar. Clay pie, already full. Up to St. Peter's Church, each person 1.5 Euros, looking around the whole Munich, the brick-red roof with eyes full, so bright and warm, just like the hospitable Munich black, it is unforgettable.
