RSAF planes have been using the Chinese "Ying Yang" Emblem since 73'
after the british forces left...
Question is..
1. Why was it chosen?
2. For what purpose does it serve?
3. What meaning does it have on RSAF Planes?
(After reading up some books on SAF, i didn't managed to find out the answer..)

Im sure alot of people here wants to know as well..
