The ancients thought that the tortoise's back armor was as convex as the sky, its belly armor was as flat as the ground, and the tortoise seemed to carry heaven and earth. Therefore, the tortoise is regarded as a spirit that can know astronomy in the world and geography in the world. Its shell is used to predict the rise and fall of life and as a mascot to predict bad luck. During the Yin and Shang Dynasties, the diviners of the emperors barbecued tortoise shells with charcoal fire, and according to the cracks on the tortoise shells, they divined for the emperors and predicted state affairs, wars, weather and disasters. The origin of the word "Bu" is that after the turtle shell is burned, cracks similar to "Bu" are easy to appear, and these cracks are used to predict fate. According to legend, the pattern of gossip is also inspired by the tortoise shell pattern of tortoise.
There are turtle lines on the back of the turtle. There are three squares in the center of the turtle pattern, representing the talents of heaven and earth, and there are 24 squares next to it, representing the twenty-four mountains, and 10 represents the ten-day stem. There are twelve squares at the bottom of the tortoise shell, representing the twelve earthly branches. Strangely, the layout of a turtle shell actually contains all the codes representing the mysteries of the universe, so the turtle is known as one of the four spirits. Turtle was called Xuanwu in ancient times, and together with Qinglong, White Tiger and Suzaku, it was called the Four Spirits Culture.
I thought it would be counterproductive to use turtle shells to turn evil spirits into evil spirits. Since the tortoise is so spiritual, can the resentment of being slaughtered disappear?
