It was April with bright sunshine and warm spring breeze. The kapok trees in the Martyrs Cemetery had already bloomed, the petals fell to the ground, and the tender green leaves hung on the branches.There are traces of grave sweeping during the Qingming Festival everywhere.

A group of primary school students wearing red scarves came to visit the tombs of the martyrs. They cleaned up the dry bouquets and leaves, and placed a rose in front of each tombstone.Peter and Su Ke, wearing police uniforms, came to Zhang Xiaobo's tomb and placed flowers in the middle of the tombstone.

Peter squatted there and took out a bottle of wine and two glasses from his bag. The glasses were filled with wine. He drank one glass first, and then gently sprinkled the other glass on the tombstone.
