"What do you mean by favorable days and locations?" Lin Tian asked, puzzled.
Xu Feibai didn't keep him in suspense and directly answered Lin Tian's question, "Our ancestors were magicians, so they had considerable knowledge about the Qiong Gou Jade. In ancient times, jade was considered noble, and imperial priests often used jade as a magic artifact for rituals. When performing rituals for heaven and earth, three conditions needed to be met: favorable days, locations, and harmony among people."
"Favorable days are determined by observing the heavenly stars, checking the lunar calendar, and calculating the auspicious days; favorable locations mean selecting a site with excellent feng shui for constructing the altar; harmony among people refers to the Emperor leading civil and military officials onto the altar to perform the ritual for heaven and earth."
