Vienna last day of play, although very hot, but not sun. In the morning, I went to Meiquan Palace, which is a royal palace. It's very elegant. In the afternoon, I went to the old cafe, Sah Cafe, and ate the Sah Cake, Austria's national treasure cake. Just opposite the tram, I was looking for the National Opera House yesterday. After eating the cake, I chose the latter in the city park to overlook the Danube River or the Danube River for close appreciation, which brought the whole trip to Vienna to a successful conclusion. Last is Maria Tracia Square and the Golden Hall in the Museum District yesterday. See you tomorrow in Rotterdam [shy]
