This is Zhou Enlai's patriotic quotation in the report of peace talks in April, 1949. The main meaning is that only by loving your own nation can you have self-confidence and the spirit of dedication to the motherland and the nation.

It means: Only by truly and unswervingly understanding the country and nation that love you, will you continue to work hard with firm faith in any difficult and difficult environment, no matter what hardships and setbacks you encounter; This is because strong national self-confidence can also be interpreted as love supporting us to continue our struggle.

Premier Zhou Enlai's life vividly expressed this sentence.
