In "Douluo Continent II Peerless Tang Sect", Qiu 'er and Wang Donghua did not formally introduce their relationship, so we are unable to confirm their relationship. According to the novel, Qiu 'er was Huo Yuhao's cousin and Wang Donghua was Huo Yuhao's friend. There seemed to be no special intimacy between the two of them, but in the entire novel, their plots and characters were closely related.
