From the names and all this looks exactly like a chinese game play.

Yes. Because according to google, HOK is the original chinese version of Arena of Valor.

like the story mood though is easy to understand one game I will love to explore

You're right! I think AOV is much harder to understand. I already tried playing that game before, and since HOK is more like ML and Wild Rift, it is easier for me to understand how to play this game. Anyway, come and play! See you there, if I see you.
