If what you are saying is true, then who can help them?

Nothing! They are doomed one way or another.

Why is it Chinese medicine's fault?
Can western medicine help them?

It is ultimately interesting to see that Koreans are trying to prove that they invented Chinese medicine and some Chinese are bad mouthing their own heritage. Listen, nobody forces you to see a Chinese doctor if you do not want to. No medicine can solve all your problems including the western medicine.

Of course, I can understand that you hate Chinese medicine if you have problems and some Chinese doctors have mistreated and delayed your treatment. However, if you just want to show you are smarter than everyone else by bad mouthing whatever Chinese has , it is not necessary.
