What do you mean by the days when the buddhas don't receive fasting in the Yellow Calendar?

: hello.

On the fifteenth day of the first month of the first year of Zhenguan, Emperor Taizong declared to his ministers: "I have seen all the surnames in the world. Every three or four days, I will set up a fast for happiness. How could there be a disaster at that time? " Master Sanzang said, "On the day of Wan's fasting. When the value meets evil spirits, it is strange, not according to the date when the auspicious qi in the Tibetan scriptures is available, so it is so. . . . . . "

In the Gregorian calendar, Ren Xu and Gui Hai Ri are "days when Buddhists don't fast, so there is no need to use them." This means that these two days are the time when all Buddha gods do not check fasting, and there is no need to set fasting.
