The Terracotta Warriors

One day I ended up in Sydney, Australia when I came across a million statue things.  Strangely, nobody was confused as they passed but me. This could mean this was natural.
Fortunately, this was more entertaining than the Opera House! The formation looked like they wanted revenge (considering their mixed colours). I could watch this all day!
But I have questions: What are they?; Why does Australia have this; What’s the inspiration? It was hilarious but confusing. Later, in a nearby hotel I saw them again. They were lighting up. “The Terracotta Warriors, those lanterns look hilarious,” said Josh. So that’s what they are…
