The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

我从不把自己当偶像看。别人的想法并不是我的想法。我只是做好自己的事而已。

I would like to fly in space.Absolutely.That would be cool.I used to just do personally risky things， but now I’ve got kids and responsibilities， so I can’t be my own test pilot.That wouldn’t be a good idea.But I definitely want to fly as soon as it’s a sensible thing to do.

绿色发展不仅是责任，更是机遇。
