These are the first time rock samples from the far side of the moon has been retrieved.

This was a fairly complex mission with autonomous docking of the sample capsule in lunar orbit and a skip re-entry back into earth.

Essentially a smaller scale Appolo mission but done with robots.

Just out of curiosity, is there any practical reason to send human to moon considering costs and risk?

When technology was less able I think there was an argument for it. I think now there is much less reason to do so. Mostly now to feed into SF dreams.
