Why Hong Kong call Hong kong?

Why is Hong Kong called Hong Kong?
Hong is 香 in Cantonese, meaning fragrant; Kong is 港, meaning harbour.
It is said that this place produced a tree called 香樹, meaning fragrant tree. But this tree no long exists because of frequent felling. So the place still retains the same old name, but because of lacking substance, it is just an empty name.

In eighteenth century, Hong Kong is a small port but it was developing quickly because the geographical features which encourage the business. Spice is major product among the all in hong kong. So people call it Hong Kong "香料港口".
