Are Ding Chou Year, Gui Mao Month, Xinhai Day and Woods Day pure yin?

According to China's traditional theory of Yin-Yang and Five Elements, Yang is the sun when the sun shines, Yang is the sun when the sun shines, Yang is the sun when the sun shines, Yang is the sun when the sun shines, and Yin is the sun when the sun shines.

Therefore, in the date you gave, the year of Ding Chou was sunny, the month of Guimao was sunny, 19 1 1 year was sunny, and the year of Wuzi was cloudy. So this date is not pure yin.
