Liu Gongquan's deeds, about 100 words, not less than 95 words,

Liu Gongquan is not only a famous calligrapher, but also an honest and outspoken person. One year, Tang Muzong saw Liu Gongquan's calligraphy in a temple, and he liked it very much. He wants to meet him and talk about calligraphy. Coincidentally, it wasn't long before Liu Gongquan came to the imperial court on business from Zhou Xia (now northern Shaanxi) and became an official there. Tang Muzong heard that Liu Gongquan was coming, so he asked him to meet him in person. One day, Tang Muzong and Liu Gongquan were talking about calligraphy together. Tang Muzong asked Liu Gongquan, "Your handwriting is very correct and vigorous, but I'm not very good at it. How can I write well with a pen? " After listening to Tang Muzong's question, Liu Gongquan thought: I have long heard that emperors eat, drink and be merry all day, regardless of state affairs. Why don't I take this opportunity to convince him? So, he said to Tang Muzong, "To write, you must first take a straight pen. The key to using a pen lies in your heart. Only when the heart is right can the pen be right! This is the same as a national event, and you can't do it without your heart! " Hearing Liu Gongquan's words, Tang Muzong knew that he was trying to convince himself with words, so he blushed.
