When Yue Fei was born, there was a red auspicious glow around the Yue family residence so neighbors brought buckets of water to put out some perceived fire. However, they found out that Lady Yue had given birth to a son. With all the people crowded around their house, a Peng landed on the roof and spread its wings over the length of the entire residence. The bird then flew high into the sky and disappeared. The sight of the Chinese roc is why Yue's father named him "Fei" (飛; "fly").
