What is this temple in Minecraft?

What's this? Are there traps? I have never seen this before. I'm only playing with this world for 3 hours, should I go in there?

This is a normal desert temple. Here's more:

Below are chests where valuable materials (emeralds, diamonds…) are hidden.

That's great, but is there any fall?

Go inside, remove a sandstone block next to the orange wool block. Go straight down, and watch out. Far below the orange wool is a pressure plate which triggers 9 TNT.

Yes, at the bottom is a printing plate made of stone. If you look at this blast trap, some TNT blocks are hidden under the ground. So you can't step on it.

Although I have no idea, but as a passionate gambler, I would simply say:

Nothing ventured nothing gained. Go inside, find out and if you die, you'll die in the game. Happens. Where is the charm to discover something, if you already know everything?
