December 21, 2012. Ye Fengluo walked on the muddy and winding path. The French paulownia tree, which has long been leafless, cannot find its dependence on the swaying in the cold wind blowing to the north. "It's really cold this winter." Thinking of this, Ye Fengsheng pulled the collar of his windbreaker with his hands, then put his hands in his pockets and continued walking towards the more winding road ahead. Around noon, Ye Fengluo finally listened at the entrance of a small alleyway paved with bluestone. He took a deep breath and walked in. Then he stopped at the third door in the alley. The red wood with gray in it, the slightly cracked lintel and the rusty exorcism mirror in the center of the door all showed that this house was Ye Fengluo's elder.
