You want to avoid getting lost if it is possible.
Especially if you are going to be finding yourself in new territories not fully explored. It’s not enough that Hong Kong doesn’t use mandarin, they also have cars going the opposite way along with confusing street signs and arrows that don’t really point left or right, but diagnal.
Moral of the story is…
If you plan to going somewhere new, know how to get there and how to get back. It will make your trip that much more enjoyable.
If you don’t mind getting lost then nevermind, have yourself an adventure!
