A teenage boy of about fifteen years old, small and skinny like a monkey, quiet and doesn't talk much. Son of Liu Congxiang and a live-in son-in-law from the Xu family. His surname is Liu, not Xu as villagers habitually call him Brother Xu. His name was given by an old scholar who came to their house when his mother was giving birth. He was born in late autumn with fair skin, hence the name Qishuang. He accidentally pushed Wan Dongyang into the paddy field in a moment of frustration. He is happy that Wan Dongyang called him by his real surname Liu. His only friend in the village is Song Saixue. He fears his miser father who owns a golden bamboo root used specifically for beating him.
