Human body week

The word "Sunday" is an ancient astronomical term. According to the principle that the human body should be a celestial body, that is, "the unity of heaven and man", the ancients introduced it into qigong practice, thinking that the celestial body is a big universe and the human body is a small universe. The sky is round, the head is round, the feet are square, the sky has the sun and the moon, and people have two eyes; There are five stars in the sky "Jin Mu fire, water and soil", and people have five internal organs "lung, liver, kidney, heart and spleen"; Talent has four seasons, and people have limbs; There are December days, and people have twelve classics; There are 360 days in the sky, and people have 360 joints.

The ancients regarded the qi-moving route of ascending after menstruation and descending before menstruation, and adopted the method of exercising on Sunday, which was called Zhou Tian Kung Fu. All kinds of internal alchemy methods since ancient times belong to the category of Zhou Tiangong. Zhou Tiangong is divided into meridian Sunday (small Sunday) and Mao Youyou Sunday (big Sunday) according to the principle that the north is in the south and the east is in the west.
