voluntary
1.I am fine. I passed a park and found there was Voluntary Blood Donation Vehicle, so I went to donate 200cc of my blood.
我很好，我刚刚经过公园，看到那边有辆义务献血车，所以我去献200cc血了。
2.So what? Japanese are always friendly to us, they were our friends in northeast during the Anti-Japanese War and I heard that some "comfort girls" are voluntary.
那又怎么样呢？日本一直对我们很友好， 在抗战期间，日本人在东北跟我们是好朋友， 我还听说有一些慰安妇都是自愿的。
