“For the sake of sacrifice, I dare to make the sun and moon change the sky.” The martyrs of Shaoshan sacrificed, but their blood was not shed in vain; Their blood brought them victory in the revolution and a new world for socialism. What great contributions they made to the proletarian revolution!

The past has passed. The miserable life in the old society has finally passed. Chiang Kai-shek’s dark rule has passed. All feudal systems of exploitation have passed and have become relics of history. "It's great to see thousands of waves of rice paddies, and heroes setting off sunset smoke everywhere." This is the scene when the sun is about to set. The people of Shaoshan have been working nervously in the fields since early in the morning.

Under the setting sun, everything will rest and the birds will return to their nests. What do you see at this time? He happily saw the rice and bean crops in Shaoshan, which were blown by the wind and set off heavy waves. Under this very beautiful scene, heroes everywhere - members of the People's Commune working in the farmland. We took advantage of the beautiful sunset and went home after a day of intense work.
