I think Chu Qiao is a man with three outlooks.
She has always had her own principles, and she is making progress. The people she killed were all people who had done bad things. In the Nine Youtai incident, she knew the innocence of the Xun Yan family and always stood on Xun Yan's side. Later, Xun Yan rebelled against Chang 'an and did many cruel things. She doesn't agree, she wants to stop her with her own actions, not blindly follow. When the Li Xiu army wanted her to be the leader, she refused, saying that there can only be one leader, and that is Xun Yan.
Some people around her say that she is a little self-righteous, but I don't think so. She just wants to change the cannibal world with her own ability. She doesn't want to hurt those kind people, such as Song Yuan and Yuan Chun. But as a person, she can't always worry about everything. She can't save the beautiful army, accompany Xun Yan to save Song Yuan and escort Yuan Chun. She can't help Yan Xun escape from Chang 'an and stay with Song Yuan, which is the opposite in itself. She can't do it without hurting anyone.
As for Yu, I always think that Chu Qiao likes Yu, but just a companion and friend. I have read this novel and admit that Chu Qiao in it likes Xun Yan. But this is a TV adaptation. I teach and love stars in his own way. And she is not a wood, she can feel that she will talk to Yu and reject him directly because her position is different. But for Xun Yan, it's love and friendship.
I wish you, like Chu Qiao, become your own sun, without borrowing anyone's light. I wish you are strong enough not to wait for others to spoil and hurt. Fortunately, someone loves you!
