I'm sorry, on this post I will call Chinese Xianxia and Wuxia under the same denomination as Light Novel since per definition they are pretty similar :
"Targeting young adults with a low depth story or quality writing."
So I just seen this post on reddit : Starting to hate all the JP-novels and I laughed. Since a good time I've seen this war between Chinese and Japanese Light Novels the same as : "Playstation vs XBox", "Console vs PC", "Microsoft vs Apple" and all others pointless wars like that.
The point of the reddit post is
"Japanese MC are coward while Chinese are realistic and takes actions".
I would say : nearly true... just remove "realistic" and you're good. NONE of them are realistic ! They are the two side of the same coin that is Wish-fulfillment just taken in a opposite point of view.
Both of them are totally stupid in fact.. Actually even if I'm not historian or cultural expert so I'm probably wrong but it make me think of their country history and cultural situation :
Of course all of that is only relevant for their low-standard writing that are light novels ; both country have totally capable writers and thinker writing true books. The same that western countries have our amateur writers on website like RoyalRoad for I-don-'t-need-too-much-my-brain-to-read.
And my personal preference in all that ? Ahha sorry, I'm more original English works. But you can check my recommendation list too.
