"read the red medicine by the bridge, and you will know who it is for every year." "Red medicine" refers to the red peony flower. Twenty-four Bridge, also known as Hongyao Bridge, is rich in red peony flowers nearby. The red peony beside the bridge is still in full bloom every year, but who are they for? It can be seen that no one has come to appreciate them. After the war, some people here died, some fled, and even those who stayed were not in the mood to enjoy flowers. How lonely the feelings of peony flowers are, and things are still like this, let alone people? There are endless meanings in the knot.
