At the very end author compares hong kong island to langkawi portraying lankgawi as some unatractive island and that hong kongers should be happy they are connected to mainland. This is where I started look more critical at the whole article having been in those islands before myself - it was a great reality check that you have read everything very critically these days.
I recommend everyone not only to check google images how langkawi look like but even more recommend to go there for a holiday [1]. It's called 'bali of malaysia' and popular tourist destination. Very close to another great malaysian island - penang.
Author says "You can rent this island for 99 years and start to develop your economy." I would happily rent it for even 10 years if the price is right!
