My Theory!
Whenever you are walking down the street and you see this chio bu (hokian for pretty woman) or this handsome young hunk walking past you...
You won't mind turning your head around and glance him/her for the second time!

It's true,won't you agree?
It's just our human nature to do this!
We,humans usually look for people with good looks!Regardless in love or in our career life next time.The very first thing that people look out for is your looks!If you aren't any attractive,they might think twice..
I'm not attacking those average or not good looking people,but it's just the fact.

"You aren't good looking either,you do you judge others?"

We people are not judges,but God is!
No matter how ugly we look,it's the perfect creation of God,and when other criticize it,God will become very upset.

My conclusion:
Why always the Handsome/Cute/Adorable/Beautiful people are always taken?
