Qian Xuesen's famous sayings:

"I am Chinese. Everything I do now is preparation, so that I can do more for the people when I return to the motherland. "What we are looking forward to day and night is that the motherland can move from darkness to light. This day has finally come. The motherland is very poor now, but it needs all of us - the sons and daughters of the motherland***. Let’s create together. We should go back.”
