Happy New Year of the OX!

Hi, my dear friends, Happy New Chinese Year! First of all, a small quiz to you:

Can you guess what it means? Let me explain it a bit. The pic is actually a Chinese word 福 written in a piece of square-shaped paper, and then rotate 180 degree. 福means happiness, “stand-upside-down” and “come” have the same pronunciation in Chinese. So by putting them together, the pic means my best wishes to you. Do you get it? J

During the holiday, I ran into a wiki page saying that the world cattle population is estimated to be about 995,838,000 head. How do they get that number? That is next challenge to you.

I will post my answer when I get one moment.
