In Chen Wu's eight words, Ren Xu is without me. Among the heavenly stems, A, C, E, G and N are sunny heavenly stems. The heavenly stem of the Lord is pure Yang, and among the earthly branches, Zi, Yin, Chen, Wu, Shen and Xu are all earthly branches of Yang. Therefore, in the Wuwu eight characters of Wuwu in Ren Xu, Chen Wu, the main branch is positive, so the Wuwu eight characters of Wuwu in Ren Xu, Chen Wu are pure yang.
