There are so many legends about the cult of Mazu and the development of Tian-Zhong, Bei-Dou area. Some of these legends are very similar, but some are not. According to the record of the Book “Zhang-Hua County Gazetteer ( Xian-Zhi)", written by Zhou-Xi, had been written about the temples of Mazu at Dong-Lou street and Yue-Xing street, but the statement is not so specific. The spread of the indefinite record and the different legends, made it hard to understand the relation of the Mazu Temples in the southern Zhang-Hua. The paper aims at clarifying various legends of Mazu in the southern Zhang-Hua through the documents recorded in the period of Qing Dynasty and Japanese Occupation, and the oral history existed after the Second World War. The paper also intends to argue the possibilities that caused different legends of Mazu at Dong-Lou Street and Yue-Xing Street. In the processes of examining relevant literature and learning the fast change of the social and religious customs, the researcher found that Mazu at Dong-Lou Street and Yue-Xing Street could be traced back to the same origin in these two areas. However, other legends, such as Mazu of two ethnic groups (Zhang and Quan) or Mazu of three ethnic groups (Zhang, Quan, and Hakka), were caused by immigration due to floods and frequent fights in Zhang and Quan areas.
