What is the meaning of "three kills" in the yellow calendar?

The "evil" here means "killing people", that is, the word "committing three murders" in China's classical philosophy is also true! For example, "ugly three-in-one western gold ~ ~ three kills oriental wood"; "Shen Sanhe Yishui ~ ~ Three kills did not open in the south afternoon."

You might as well look at the calendar, where the fourth day, unitary day and ugly day must be "evil east"; The day of the sea, the day of the night and the end of the day will be "sad"; God's day, son's day and Chen's day must be "south"; Yin day, noon day and night day will be "evil".
