林嘉欣 vs 林嘉华

Just heard from the radio some interesting facts.
We only see half of the moon surface all the while coz the moon is circling the earth. As we know, the moon surface is rough, like the volcanoes. So, Chinese always like to say if you have pimples all over your face, you'll have a face like the moon's surface! However, one will wonder how will it look like, the other unseen side of the moon? Is it the same or different?
The fact was, it was completely different, as the other side is hilly and full of mountains.
So, conclusion? 林嘉欣 vs 林嘉华
