What do the left and right hands of Yin-Yang diagram mean?

The congenital Tai Chi map from Chen Tuan is a left-handed Tai Chi map, which is mainly popular in Taoism (Taoism believes in the unity of heaven and man, with the celestial phenomena as the mainstay, the Beidou starry sky is left-handed, the North Star is above, and the sun is below). Fu set up a pole in Dadiwan area to measure the day, and drew a right-handed congenital Tai Chi map based on Confucianism (Confucianism thought it was the south, with the sun fire above and the moon water below, and inherited the right-handed Tai Chi map, such as the emblem used at the International Yi-ology Conference and the Tai Chi map on the China Millennium Monument in Beijing), and published it in Ni's Children Easy to Go Abroad in the Ming Dynasty. Left-handed and right-handed people are unified, and the difference lies in the environment and psychological orientation of the observer. Now it is found that the Taiji image carved on the ancient rock paintings in Lianyungang more than 6000 years ago is left-handed.
