As you say, it's just your opinion, but you express it strongly with more than a hint of sarcasm. And that's on the basis of having lived only a few years in an Asian country and never having spent much time in Japan, let alone having worked there.

As for the reference to Chinese, it was of course meant in a business sense. For all my time in Hong Kong and Japan has been business-related.

But then you are the expert and you have your opinions of what other posters write and express as the truth.
