Vienna is the most gentle and beautiful dream to me, for I fell in love with Princess Sisi when I was young. Thus, when I stepped into this mountainous country, it was like touching those childhood memories. This place, known as the heart of Europe, presents its splendor after a thousand years. Vienna has just entered winter in November, and the air is filled with the aroma of coffee. The Austrians even equate coffee with waltz and music, referring to them as the "three treasures of Vienna".
