Da Tou Ge: The origin of the poem's ambition is to break through the wall and find it difficult to gain rewards, and to be a hero across the sea.

"After the Great River Song, Turn Head East" is a seven-character quatrain composed by Premier Zhou Enlai in 1917. This poem fully expresses the author's lofty ambitions in his youth and his revolutionary spirit of dedicating himself to the cause of national salvation.

Original text of the poem:

After singing the big river, turn eastward,

Sophisticated science and technology help the poor in the world.

After facing the wall for ten years, I tried to break it,

It is difficult to reward a hero even if he crosses the sea.

The meaning of poetry is: singing heroic songs to travel eastward to seek truth, and studying social sciences intensively to save the country from crisis. Studying hard in the face of the wall and striving to overcome the hardships and hardships is difficult to achieve the ambition of crossing the sea. Going abroad to seek the truth is also a heroic act.
