The anniversary of Yang Gong's death is another auspicious day.

The old custom began on this day of the lunar calendar, and then two days in advance every month is Pepsi Taboo Day, which is called "Yang Gong Taboo Day" and also known as 13 taboo in Yang Gong. Biography was written by Song Yang, a geomantic master in Tang Dynasty.

These thirteen "taboo days" are 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 July, 27th of August, 25th of September, 23rd of October, 21st of November and 19th of December.

Don't choose to start business, construction, get married, sign contracts, etc. in these 13 days.

Although one day may be an auspicious day in the Gregorian calendar, it is suggested to avoid this day because it conflicts with the anniversary of Yang Gong's death. If you don't choose the anniversary of Yang Gong's death, you can find a way to solve this problem.
