According to my fortune-telling, all my constellations are Yang.

The eight characters are composed of ten heavenly stems and twelve earthly branches, among which A, C, E, G and N in heavenly stems belong to Yang, while neutrons, Yin, Chen, Wu, Shen and Xu in earthly branches belong to Yang, while the other five heavenly stems and six earthly branches belong to Yin, and your eight characters are all Yang, which means that the year, month, day and time of your birth are represented by earthly branches. See if your constellation is made up of branches belonging to Yang!
