Li Ying's Sunset on the Yellow River is rich in content and full of strong patriotism and optimism. Why wait five thousand years to see the sunset on the Yellow River? Because the hardships, sufferings and disasters of this yellow land for 5 thousand years have been taken away by the sunset, the new sunrise has brought new hope to this great land. The Yellow River is the witness and clue of history. The setting sun of the Yellow River is a tragic scene, crossing the darkness and the long night to welcome a brand-new sunrise.
