They became friends by going to the same school. Lưu Bình was born to a rich family. Because he took things for granted, he was not interested in studying. However, he supported Dương Lễ materially as Dương Lễ was very poor. Dương Lễ studied diligently, then passed the Imperial Examination and became a royal official while Lưu Bình failed and eventually wasted all his fortune. Lưu Bình became homeless and a beggar. One day, Lưu Bình went to Dương Lễ to ask for help. Instead of welcoming Lưu Bình to his house, Dương Lễ did not show up but sent his servants to serve a terrible meal to Lưu Bình that made Lưu Bình so mad. Feeling desperate, Lưu Bình wandered around and stopped at a small restaurant. The restaurant owner was a young lady named Châu Long. Châu Long, after hearing Châu Bình’s story, agreed to take him in with a condition that Châu Bình would study hard, prepare well for the next imperial examination. Lưu Bình, being touched by Châu Long’s gesture and feeling ashamed, offended by his old friend, decided to study hard. He finally passed the highest examination and was well respected. He came back home to look for Châu Long but she was gone. He then went to Dương Lễ’s house in order to show off his new status. In surprise, he met Châu Long who was actually Dương Lễ’s wife. Dương Lễ had secretly sent her to help Lưu Bình. The way he treated Lưu Bình so badly before was also in his plan to help Lưu Bình to change his life. Lưu Bình realized the tough love that Dương Lễ had given him. The two came together and their friendship was reborn.
