I have a challenge, can you distinguish which character set/s belongs to Japanese & Mandarin?
There are of course differences between Kanji / Hanzi but the “difficult” part is knowing which language is which simply by glancing (unless you know either 日本語 or 中文 that is).
In contrast, do you know any words that are near identical when written down between two “alphabetical” languages based on their spelling?
I can tell, but that’s because I can read both. Someone who’s never learnt either language probably can’t tell the difference between the sinographs, but could distinguish the language based on presence of hiragana, which are distinctly rounder and less dense
