"Ding Fengbo"

(On March 3rd, it rained on the Shahu Road. The rain gear went off first, and everyone in the group was in a panic. I didn't realize it. It cleared up, so I did this on purpose. )

Don’t listen to the sound of beating leaves through the forest, why not just scream and walk slowly. The bamboo stick and mango shoes beat the horse easily. Who is afraid! A coop of mist and rain will last a lifetime.

The steep spring breeze blows away the drunkenness, it is slightly cold, but the mountain tops are shining slantingly. Looking back, I have always been in a bleak place. When I returned home, there was no wind or rain or sunshine.
