For those that don't know why China crashed the probe, I will inject a bit of insite.
The way a space program works, is first, try to find out if you can get a probe NEAR the moon. Then try to fly it all the way to the moon and orbit it. After you orbit, then you try to pick where it lands (aka crash it at a precise location). The next step is to send an unmanned vehicle to an exact spot and bring it back (getting there is fine but if you can't get back, you are sunk). Then you try a manned probe to orbit the moon and then come back. Finally you send a manned flight to the moon land collect samples then go back.
Ever wonder why it was Apollo 11 that had the first man to walk on the moon? It isn't as simple as aiming a rocket and shooting...
