They said that they were not valued by the Emperor of Xiyun, and although they seemed to have the status of a Commandery Prince, they actually held little esteem and were often ridiculed; meanwhile, Linghe had already borne a son for the Emperor of Chilin and had established a strong foothold in Chilin. Hence, they were considering moving to Chilin.
Even more, the second daughter-in-law knew where the Prince of Pingjun and Linghe's secret letters of correspondence were kept.
And in those letters, Linghe was urging the Prince of Pingjun to leave Xiyun and defect to Chilin.
In her letters, she also mentioned that before defecting, the Prince should establish some achievements for the Emperor of Chilin, ideally a significant one, like securing the raw materials for making white paper. This would greatly please the Emperor, ensuring that upon their defection, they would not only be warmly welcomed but she might also be likely to ascend to a higher rank.
