"... In his twentieth year Shun attracted by his filial piety the notice of the wise and virtuous Yao, who bestowed on him later his two daughters in marriage, and disinherited his" (unworthy) "son, Chu of Tan, in order to make Shun his successor upon the throne."  P. 165:  "Ngo Hwang, sister of Nu Ying, with whom she was given to the virtuous Shun to wife by her father, the Emperor Yao, in B.C. 2288 (?).  A pleasing tradition relates that the two sister-queens, having accompanied their lord on his journey to the south, during which he died in the land of Ts'ang-wu, wept unceasingly as they bent over his tomb; and their tears, falling on the stems of the bamboos around, became transformed into the spots which adorn the variegated species of this plant.  The monarch's grave was near the river Siang, and hence the spotted bamboo is called Bamboo Siang, and the two princesses have become deified under the title Siang Fu-jen."...
