1. I am from China. Everything I'm doing now is making preparations, so that I can do more for the people after I return to my motherland.

Feelings: Although Qian Xuesen is in a foreign country, he is preoccupied with the motherland and wants to serve and contribute to its development. From it, we can read his ambition to serve the country.

Feelings: Qian Xuesen didn't complain about the poverty of his motherland, but he was willing to give up his superior conditions in the United States and return to the poor and white motherland, from which he could read his ardent patriotism and nostalgia for his motherland.
