They are “Kun Ren Yi (坤壬乙) should start from the star Ju Men (巨门)”;“Kun Ren Yi should start from the star Wen Qu (文曲)” and “Kun Ren Yi should start from both the star Lian Zhen and the star Ju Men (Lian Ju (廉巨))”. Because of the sectarianism,though the people were at odds with the opinions, we cannot find out any comprehensive and objective study on these. According to the analysis of some relevant literatures, it can be seen that there are two viewpoints nowadays. One of the viewpoints deemed that the first sentence was falsified by Jiang Da-hong (蒋大鸿), and another one deemed that was falsified by Zhang Shou-qi (张受祺). But neither of the view was credible. More precisely is that “Wen Qu” and “Ju Men” were both found in the publications simultaneously, and there were more “Wen Qu”, during the period of the end of the Ming Dynasty and the era of the emperors Kangxi and Qianlong of the Qing Dynasty. The influence of “Ju Meg” was gradually spread when Jiang Da-hong used it in his book and also Si Ku Quan Shu (四库全书) cited it, then let to more pithy formulas of “Ju Men” to be used now. And the “Lian Ju” was rare to be used except Duan Mu Guo-hu (端木国瑚) who used to use it. The way of interpretation is so multiple and complex on the “Wen Qu” and “Ju Men” from the Qin Nang Ao Yu, according to the perspective of Feng Shui, which is reflecting the pluralism and uncertainty of the interpretation of the traditional Feng Shui. And it is still need to be required a further more careful consideration on how to treat the studies of the traditional Feng Shui for the nowadays scholars.展开更多
