Hello, everyone, I am Mr. Fang. Now imagine a scene like this. This is a very pleasant season, a season where you can wear whatever you want. Two people, one wearing a down jacket and the other wearing a warm suit. Pants, two people walked towards each other in the small alley. When they saw each other, they laughed loudly, leaned forward and backward, and after laughing, they said: "This guy is very sick." Who is not sick depends on who is suitable for this season. This is A complicated season, however, clothes can be worn randomly, and the frame and structure can be designed randomly, hehehehe.
