When the blizzard first fell at the end of 2007, I was on my way to Shanghai. Because the road ahead was blocked, the car was stuck for three days and nights and took a long detour. Along the way, those water towns in the south of the Yangtze River that I had only seen in my dreams appeared in front of me one after another. In an instant, the vastness of life and death, and bits and pieces about those places, past and present life, kept flooding into my mind. Six cities, six classical memories.
