Various countries have been sending unmanned probes to the moon since 1959. It's not eventful just because China managed to repeat what the Soviet Union and USA did decades ago. It's great that the Chinese accomplished it and they should be proud of their efforts, but so what.

You can't force ordinary people to care about every single space exploration mission. It doesn't impact their lives.

Maybe it is just that sending a robot to the moon doesn't count as "having been on the moon", else the EU, US and USSR would "have been on the Mars" already.

The Soviets landed unmanned craft on the moon too[1], not to downplay China's success. I would imagine most people tend to think of the Apollo landings and nothing else, since getting people there and back in one piece is fairly significant.
