Shun, a legendary ancient emperor and one of the Five Emperors, had a surname of Yao and a last name of Chonghua. He was also known as Yushi or called as Yushun in Chinese history.
According to the legend, his father Gusou (literally the blind old-man), stepmother and half brother Xiang plotted to kill him for many times:
They let Shun revamp the roof of granary and set fire under the barn, Shun jumped to escape with two bamboo hats in hand; they also let Shun dig a well, but Gusou and Xiang filled soil to the well while the digging, Shun then dug underground tunnel to escape.https://www.ienglishcn.com/
Afterwards, Shun didn’t resent and was still humble to his father and loved his younger brother.
His conducts of filial piety moved the King of Heaven. When Shun cultivated in Mount Li, elephants ploughed for him while birds weeded for him.
Emperor Yao heard that Shun was a filial son with the talents of dealing with political affairs, and married off his two daughters, Ehuang and Nvying, to Shun.
Through years of observation and tests, Emperor Yao selected Shun as his successor. After Shun ascended the throne as the Son of Heaven, he still called on his father respectfully, and granted the leud title to Xiang.
