It's a big park. It's cold in the afternoon. Owing to his husband's preference for this period of history, he took a long walk when the tour bus was out of service. From Danfeng Gate to Xuanwu Gate, the snowflakes still drift away. Under the snowy sky, Xuanwumen is both lofty and lonely, which makes people sigh. History is gone forever, but people are small and things are still there.
