Does the sentence sound natural? Need editing? If so, do it please

It's unnecessary to repeat speakers.
The first sentence is a bit convoluted, overkill. A native english speaker might say.
A native english speaker can't understand you, nor could a native Chinese.
Or
Neither native English or Chinese speakers could grasp what you intended to convey.

Neither can native English speakers understand you nor native Chinese fully grasp your meaning

Good one.
Thanks

Not at all, Or
Obviously you're very perceptive

Then improve it or make a new one please.
