according to the traditional twelve earthly branches in China, Shen is a time in the earthly branches, corresponding to 3: p.m. to 5: p.m.. This time period is considered as the time of Wushen. In the traditional culture of China, every moment has its specific symbolic significance and influence. The time of Wushen is considered as a time when the yang is fading and the yin is getting longer, which represents the characteristics of the afternoon in a day. During this period, people believe that the yang spirit begins to turn to the yin spirit, everything gradually returns to peace, and the human body also enters a relatively calm state in a day. The time of Wushen is of special significance in the traditional culture of China, and it has been used in the calculation and analysis of numerology and geomantic omen.
