Guan Cai was a fisherman who played the flute well and had a beautiful voice. Huang He was a beautiful young lady who lived in the embroidered building of a mansion by the Yellow River. She especially loved listening to the sound of the flute. As time went by, the two of them became friends. Suddenly, one day, the young lady's father betrothed him to a wealthy man. The young lady was absent and imprisoned. She missed the manager and fell ill! Guan Cai couldn't see Huang He, so he died of depression. Before he died, he asked someone to bury his heart in the grass below the lady's building, so that he could stay with her all day and night. The lady's father offered a reward for medical treatment, but no one could cure him. A southerner who knew Feng Shui passed by the grass field late at night. , seeing the flash of light, he took Guan Caixin out of the soil with a sandalwood box, and he was still alive. On the second day, I received the order for treatment. I put Guan Cai's heart in the clean water to cover it with a screen in the lady's study, and it floated up, making a melodious flute sound. When the lady heard the sound of the flute, she thought that Guan Cai was coming. She gradually got better and got up to watch. His heart saw Huang He sinking to the bottom and dying. Huang He shed tears when he saw Guan Cai's heart. But he couldn't see Huang He's determination not to give up, and he couldn't see Guan Cai's intention not to shed tears.
Interpretation: A metaphor for not giving up until the goal is achieved. It is also a metaphor for not giving up until there is really no way out.
