When Little Iron Armor Meets the Third Prince

As Iron Armour turned out of Apliu Street,
he encountered a lost little boy.
 

"I know this area like the back of my hand!
Tell me, what's your house like?"
 

"My house, it's fragrant and bright,
with a tree in front and dragons on the roof!"
 

That sounds like a lot of clues!
They wandered around Sham Shui Po, playing and searching.
So where exactly is this new friend's home?
