YY does another interview, in the caption it says he talks about “ In a recent interview, he said that Zhan Zhao's "strength" lies in the precision and crispness of his movements, as well as his unyielding resilience in the face of injustice; his "gentleness," meanwhile, is reflected in his reluctance to harm the innocent and in the youthful spirit he brings to his friendships. In his eyes, true chivalry is not merely indulging in righteous vengeance, but rather, even when the path ahead is fraught with hardship, still choosing to uphold justice. Zhan Zhao wields his sword and roams the world, rising to the occasion in defense of justice; the very essence of the "xia" has remained unchanged. Reflecting on his acting career, Yang Yang said he has grown increasingly respectful of the profession and will remain true to his original aspirations, delving deeply into each role and repaying audiences with more outstanding works.” https://weibo.com/1699432410/5302416209347978
