The reason why Ying Si chose Ying Dang and not Ying Ji was different and controversial. There was a saying that Ying Si chose Ying Dang because Ying Dang was braver and more courageous than Ying Ji. Another theory was that Ying Si chose Ying Dang because Ying Dang was smarter and more flexible than Ying Ji. Regardless of which statement was correct, Ying Si's final choice of making Ying Dang the crown prince might have been due to various considerations. Ying Dang was the eldest son of Ying Si, the legitimate son, and also the son of the queen. He had the legal right to inherit the throne. In addition, Ying Dang had shown a strong and unruly character during his growth, which might have made Ying Si believe that he could rule Qin better. In addition, Ying Si might have also considered that if he chose Ying Ji to succeed the throne, it might lead to internal strife and be detrimental to the development of Qin State. Therefore, Ying Si chose Ying Dang as his successor instead of Ying Ji.

Therefore, it could be said that the relationship between Ying Dang and Ying Ji was good at a certain time, but it changed later on.
Si Teng and Bai Ying separated because of a disagreement in their relationship. Bai Ying liked Shao Yan Kuan, but Si Teng didn't like him. In order to pursue his own feelings, Si Teng chose to split into his second personality, Bai Ying. In this way, Si Teng and Bai Ying became two completely different individuals. The split between them was not the result Si Teng wanted, but it happened passively. Si Teng knew that she was about to die, but she didn't want to use Bai Ying's power to save her, because that way, even if she was revived, Shao Yan Kuan would die. In order to realize his and Shao Yan Kuan's dream, Si Teng chose to use the seed to split himself into Si Teng and Xiaoxi Zhu. In this way, Si Teng could live a normal life, while Bai Ying would lose her past memories.
