Recommend to you the works of several Japanese soundtrack masters. Their works have a more classical and Japanese style, and their works are often quoted in Chinese costume dramas

"The Dawn of Heroes" by Yokoyama Keiji (the opening song of the Three Kingdoms, used in many TVB martial arts dramas)

"The Original Scenery of Hometown" by Soujiro (also a song often used in TVB martial arts dramas) )

"Memory of the Forbidden City", "Elegance", "City of Sadness", "Whispers", "Sea Goddess" and "Southern Cross" by Shensi Zhe (there are too many from Shensi Zhe... many of them are in ancient costumes The one used in the play is bad)

"Seven Swords War Hymn" by Kenji Kawai (a majestic and shocking song) "Song of Memorials"

"Asika" by Joe Hisaishi "Miscellaneous", "Infinite Love", "HANA-BI" (Hisaishi Joe's songs are all great)

Himegami's "Thirteen Spring", "Snow Score", "Earth Flame", "Koharu Hiyori" and " Poem of the Gods"
