Legend has it that there was a beautiful woman named Yuehua in ancient times. She was blessed with natural beauty, purity, and a kind heart. She received a good education from a young age and was proficient in music, chess, calligraphy, and painting. She was gentle, elegant, knowledgeable, and reasonable. Yuehua's father was a prominent official, and he hoped that Yuehua would marry a wealthy young man from a prominent family and live a luxurious life. But Yuehua did not like those extravagant young men. She had her heart set on a poor scholar named Shusheng. Shusheng was a talented and learned man, who, though poor, was honest and kind, with a pure heart. After Yuehua and Shusheng met, they fell deeply in love. They often took moonlit walks together, recited poems, chatted, and their love for each other was very deep. But Yuehua's father was strongly against them being together because he believed that Shusheng was too poor to marry his daughter. For the sake of love, Yuehua resolutely broke away from her father and chose to elope with Shusheng. They lived a poor life far from their hometown, but their love was stronger than ever. Yuehua and Shusheng supported each other and spent the best time of their lives together. With their actions, they proved the power of love and showed the world their unwavering loyalty to each other.
