In this article, I reaffirmed that “November 16 Byung-o(丙午)" on the seven-branched sword(七支刀) is not one of (吉祥句) that is irrelevant to a date, from an analysis of (漢三國西晉紀年鏡銘集釋) which interprets comprehensively the collection of mirrors(紀年鏡) in Han, Samkuk, and Seojin period. Especially we should pay attention to cases such that all dates are displayed on the seven-branched sword. Among them, the cases the Kanji(干支) and the date do not match were as follows : '"First year of Gyungnyung September 9 Byung-o(丙午)", "22nd year of Gyunan October 10 Byung-o(丙午)", "24th year of Gyunan May 30 Byung-o(丙 午)", "First year of Juko May 20 Gap-ja(甲子)." It seems that Byung-o (丙午) is connected to an auspicious day such that September 9th implies the date the sunlight is the most strong, 10 is the perfect number, and 20 and 30 which are a multiply of 5. On the other hand, among the cases the Kanji(干支) of Byung-o(丙 午) and the date match were as follows : "7th Year of Hipyung January 25 Byung-o(丙午)", "4th Year of Gwanghwa January 13 Byung-o(丙午)", "5th year of Hwangmu May 7 Byung-o(丙午)", "5th year of Gahwa May 5 Byung-o(丙午)", "Second year of Gyungnyung January 27 Byung-o(丙午)." Although a multiply of 5 or 7 which implies a lucky number is uses as May 5th, we can observe that 13th or 27th corresponds to the actual calendar rather than meanig the lucky number. Also there is no case that 11 or 16 is used as Byung-o(丙午) such as 'November' or 'the 16th day'. Furthermore, in the case of "22nd year of Gyunan October 10th Byung-o(丙午)", it used 'October 10th Byung-o(丙午)' even though ‘October 16th in 217' was correspond to the Kanji(干支) of Byung-o (丙午). It means that the 16th was not regarded as the good day, so it is 日干支different from the actual calendar. Thus, the case of the “November 16th Byung-o(丙午)" on the seven-branched sword(七支刀) was not used as 吉祥句. In this context, the year of production of the seven-branched sword (七支刀) was confirmed on the 16th of November, 4th year of Junji(腆 支), 408 corresponding to the regime of 銘文checking whether November 16th is related to the period of the Kanji(干支) of Byung-o (丙午).
