How to explain the love between Dou Jingtong and Li Yan?
Mi Yue said: In the early days of the ancient times, people only knew that there was a mother but not a father, so there was no such thing as fratricide. When people knew that there was a father, there would be fratricide. It is natural for brothers and sisters to obey their mother, but it is only a matter of interest for them to obey their father. Therefore, most of the "siblings from the same mother" are brothers and sisters, and their love is as deep as the sea. However, the "siblings from the same father" were motivated by interests in ancient times and killed brothers and fathers, which has become more and more serious now.
