No problem~ Please feel free to ask more public transportation question if you have any in the future.
HK's bus system works similar to New York's subway. There are express bus, local bus, limited stop bus, and commuter bus. They are very frequent when service is provided during the day except only a few bus routes providing service every 30 minutes.
Even people who live in those less crowded or suburban areas, they still usually have access to the public light bus with 16 seats, namely green or red mini bus.
This might be helpful if you want to notify the mini-bus driver of your destination...
