As the previous comment says, you're the one with reading comprehension problems. The topic of discussion is the replacement of Chinese characters with a phonetic writing. I said that pinyin already exists and it has not replaced characters, so this cannot be easy as you imagine (just writing down the phonetics of the language).

Which is your perspective, and distinct from the argument just made: that if it was possible to write Chinese tones, the traditional characters would have been replaced. It's obvious that the characters are not replaced due to cultural factors, rather than the inability to come up with a system that can transcribe Chinese speach.
