When Liu Bocheng was a child, his family was very poor. Later, his father died of illness, and the family became increasingly poor. One year during the Spring Festival, the family couldn't even open the pot. That night, the family tossed and turned and couldn't sleep. My mother sighed and talked about the past: "When your father was alive, every few days before the New Year, he would go to the street to write Spring Festival couplets and sell them. He could always exchange them for rice and vegetables. He could barely make ends meet. It's the New Year, but now..." The mother's words reminded her son. Liu Bocheng got out of bed and said, "Mom, I will also go out to write couplets and sell them tomorrow!" After hearing this, the mother shook her head first, and then thought about her son's calligraphy pen. He has some skills in calligraphy and is somewhat famous near and far, so he might as well give it a try. The next day, Liu Bocheng took his younger brother as a helper, picked up the "Four Treasures of the Study" left by his father, and came to the small village of Zhao's family. He borrowed some big red paper on credit, borrowed a small table, and set up the stall. He hung up the regular script "Spring Festival Couplets" and "Auspiciousness" written in advance to attract customers. Then, he stretched his right arm and wrote more than 10 couplets in a row for passers-by to watch and choose. After a while, a lot of people gathered around, and they all commented: "You are so young, but you are very talented! You can hang out, you can hang out..." After a while, all the written couplets were sold out. Liu Bocheng continued to write.
