Hi, I’m Xu, Yunxin, I decided to measure the time of leaf falling from a tree on the street behind our campus.

The time is 5.95 seconds, so I get the number 5, 9, 5, so I went to the nearest bus station in the direction from tree to the leaf.

   

and then wait for the fifth bus, took 9 stops, and I took photos of the area within 5 meters around me.

  

This bench is the first thing I noticed when I get off the bus, so I will take this bench as my idea resource, and this is my brainstorm about the bench.
