Brave people are not those who don't cry, but those who are willing to run with tears in their eyes.

People's hearts should be like a vast sea. Only by constantly accepting the rivers of hope, courage and power can the splendor last forever. We also feel from the tears of a scientist that a person is willing to devote his life to his ideal and unswervingly. Brave people are not those who don't cry, but those who are willing to run with tears in their eyes.
