I think it's a very good topic for discussion. I have always been a big fan of long hair. It adds much more appeal to them. I could make a very long list because I am a big fan of historical dramas. Here are some of them:
Alen Fang (Love in the Desert 2024, especially with tribal hair ornaments and brides.)
Zhang Linghe (My journey to you)
Luo Yunxi (till the end of the moon)
Xiao Zhan (The Untamed)
Yang Yang (Love O2O / Once Upon A Time (2017))
Shawn Dou (Princess Agents)
