New Territories is an interesting place, where you'll find the most scenic places in Hong Kong + low/ middle density industrial areas + landed properties + crowded public housing estates + cheap shops etc... It is similar to Bedok, but with more nature surrounding it.
It was a short trip, mainly because there wasn't much to see, and also because the weather took a turn for the worst and the Yellow Rain Signal was hoisted later on.
Nevertheless, it is always better to walk around rather than being cooped up in the room, now that school is over.
