It is the chirping of cicadas in the hot summer and the innocence of a group of teenagers

The unsolved math problems in the summer are also buried under the dead branches and leaves

With countless dreams and springs of fantastic ideas

I was catching the No. 12 bus in the red coat in the dark

But we are by no means the broken branches and leaves that cannot withstand the wind and rain
