Yang Gong's Death Day, a geomantic term, also known as "Thirteen Taboos in Yang Gong", was determined by Yang Junsong, a geomantic master in the Tang Dynasty. They are January 13th, February 11th, March 9th, April 7th, May 5th, June 3rd, July 1st, July 29th, August 27th, September 25th, October 23rd, November 21st and December 19th. In the eyes of Xuan Kongjia, these thirteen days can never be chosen as opening, construction, marriage and signing contracts.
There are two different opinions about the specific date of Yang Gong's death. One person said that the anniversary of Yang Gong's death, exactly this month 13, must be noticed, especially not to travel. Another way of saying this is that "Thirteen Taboos in Yang Gong" refers to thirteen "taboo days", namely the 13th of the first month, 11th of February, 9th of March, 7th of April, 5th of May, 3rd of June, 1st of July, 29th of August, 27th of August and 25th of September. It is unlucky to do nothing on this day of every month.
Legend of origin
In ancient times, there was a family named Yang who had 13 sons, but his neighbor had no sons. Therefore, he often puts on a smug look in front of his neighbors. The neighbor was very angry and cursed him: "Don't be arrogant and don't show off. Birth, illness, death, each has his own life. Who knew your son would live a long life? " Yang Gong laughed, "Haha, I have 13 sons. Even if I encounter three disasters and six difficulties, I am not afraid. Even if God is jealous of me, he will take one of my sons away every month and leave one to die for me. "
Unexpectedly, by coincidence, there was a plague one year, which happened to be a leap month. Yang Gong's son got a plague, and his eldest son died on the 13th day of the first month. Then, the sons died one by one. By the end of1February, Yang Gong's 13 sons had all died, leaving him alone, and the scene at night was very bleak. People say that everything that happened to Yang Gong was due to his own boasting. At the same time, the number thirteen is also considered an ominous number.
