Finally, China begins sea trials of its first aircraft carrier.
What are the true value and functions?

1. Training and emulation
2. Scared off not the US but south east countries like Vietnam (don't steal my OIL)
3. Travel around the world and show off  

i think it's only a try sailing,because the carrier have so many equipments to set,next,it will be equiped with that

that is a good question. I guess it wanna demonstate its power.

more power is good for the country.
