Yang Wei and Phillip... brothers?

I was watching the Men's All around olympics... (yes its sadly that homoerotic) but i really wanted to watch it to cheer on my friend Phillip (AKA YANG WEI)
I cant tell the difference... can you?

Both are Strong
Both are Chinese
Both have Faux Hawks
Both are Pale
Same Height
did i mention they are Chinese???
so the real story is... was phillip adopted like a baby shilo and seperated from his twin?
