Ithaca, the United States winter, is relatively cold, last winter, and encountered several heavy snow, this is the biggest snow I have ever seen in my life... When I woke up, the snow buried my ankle. The sky was blue for a while, and the sky was clear for thousands of miles; for a moment it was cloudy and snowy. It's like a kaleidoscope. It's beautiful. The fourth one is the Cornell University School of Architecture. It's very beautiful.
