Lu Li-cheng, director of the office of exhibitions at the Taiwan Museum of Prehistoric Culture, who has done a study on "The Recognition and Categorization of Time" among various peoples, stresses that choosing an auspicious day is by no means something for the foolish. Everyone from the emperors of yore to the official elite of today subscribe to these beliefs.
對人類「時間的認知與分類」做過研究的台灣史前文化博物館展示組組長呂理政也表示，擇日不是愚夫愚婦才做的事，古代的皇帝、現代的達官貴人，幾乎沒有人不信。
