i usually don't like historical dramas but i wanna get into them. i'd prefer if it's Chinese or Korean since I have not watched historical dramas made by other countries yet

The Red Sleeve? It was quite popular (and beloved) when it was airing. But if you want something fluffier, maybe Moonlight Drawn by Clouds?

What other genres you want them to be? (comedy, political, romance, fantasy... )? All historical I saw and could recommend:

Korean:
Splash Splash LOVE - short romcom
Jesters: The Game Changers - comedy movie
Rebel: Thief Who Stole the People - supernatural drama, romance, thriller
Kingdom - horror, zombies
The Tale of Nokdu - action, comedy, romance

Chinese:
Eternal Love of Dream - fantasy, romance, Xianxia (magical beings and gods and other immortals)
Joy of Life - mystery, romance, Wuxia (martial arts)
Love Like White Jade - mystery, romcom
Douluo Continent - fantasy, action, friendship, XuanHuan (magical beings without immortals)

historial is a pretty broad category.. I'll give you both my lists of Chinese & Korean favs, but I like a huge variety of tropes... but watch a ton of serious and possibly tragis dramas LOL
