Chen Goudan, who later changed his name to Chen Feng.
He lived in the Qing River Brigade and was one of Gu Qingyao's good friends. Chen Goudan's parents died long ago, and he and his younger sister lived with their oldest uncle. The oldest uncle's family bullied them since they were young. Later on, they moved out to live by themselves. They got through the hardest years with Gu Qingyao's help!
After they left, Chen Xiaocao and her older brother, Chen Goudan changed their names together. Chen Goudan called himself Chen Feng, and Chen Xiaocao became Chen Qingqing.
Chen Xiaocao was still very young when all this happened. Now she had grown up, and her features had changed. This was why Gu Qingyao felt that she was familiar but did not recognize her.
But when Mo Beihan said her name, she immediately remembered her.
"That's right, it's Qingqing. Go get the medical kit. I'll take a look."
