"Feitian" is a god who can fly in the sky in religious legends. He is highly respected among the people and represents the simple people's wishes for life. People have always maintained "painful hope" in the situation of poverty. For thousands of years, they have been hoping that their prayers for a better life will "fall to the ground" and become a reality.
Therefore, you might as well insert a picture that upholds hope, not necessarily the Feitian in the mural, because the poem itself also puts double quotation marks around Feitian, so more attention should be paid to its extended meaning
