Traditional Chinese medicine family descendant Song Qinghe took in Li Dehou as a resident son-in-law, with the agreement that the children would take the mother's surname. At the grandfather's funeral, the son publicly changed his surname to Li, and the father and son plotted for the Song family's hundreds of millions in assets and the clinic. Song Qinghe feigned agreement, filed for divorce based on premarital property and a will, and drove the two out of the house. She welcomed back her illegitimate son Song Nian, who had been fostered out in his early years, to prepare to inherit the family business. The ancestral recognition ceremony was disrupted by Li Dehou's family, and Song Qinghe exposed his many years of bad deeds. Li Mingyuan woke up to reality in remorse but could not turn things back, and mother and son completely broke off relations. Li Dehou and his son made a destitute living, while Song Qinghe and Song Nian lived a stable life.
