Xie Ying and Xie Lin were found by Xie Shan in the icy and snowy land, though they were adopted daughters, he doted on them more than his own.
Since he was a man, not suited for raising and caring for two baby girls, he took them to Fairy Immortal Biwu, Cui Wu, for help, who then became the nurturing mother to the two girls.
When the two girls made mistakes, Cui Wu would harshly reprimand them, and Xie Shan would always help to plead for them. If the mistakes were too grave, they would sneak away from Immortal Mountain to Wuyi Mountain to ask their father for leniency.
No matter how big their mistakes were, as long as they rolled into Xie Shan's arms and acted spoiled, Xie Shan's heart as a loving father would melt, and he would immediately protect them.
These two daughters were a bond accumulated from Xie Shan's past life, a natural extension of his character, knowing only to indulge excessively.
