所以我想特別談及呢個例子 ， 因為呢個確實係非常唔錯嘅觀察結果 ， 30 年前 ﹐ 冇錯 ﹐ 係 30 年前嘅結論 ﹐ 而一直冇被發揮 ﹑ 利用嘅 ﹐ 就係呢個結論 。
So I want to talk about this example in particular, because this is really a very good observation, 30 years ago, yes, it was a conclusion from 30 years ago, and it has not been used and it has not been used, and this is the conclusion.
