Xiao Rang, a master scholar, was nicknamed because he was good at imitation? what do you think?

Xiao Rang, a middleman in the Water Margin, is known as the master of Wenxing. At that time, a famous calligrapher in the Northern Song Dynasty knew all kinds of fonts like the back of his hand. When Sung River was caught in Jiangzhou, Wu Yong asked Dai Zhong to invite Xiao Rang and Jin Dajian, a jade arm craftsman, to Liangshan to forge Cai Jing's documents, hoping to save Sung River. Xiao Rang was good at calligraphy and imitated many people's calligraphy, so people at that time called him a master scholar. He can also use a good gun and wield a sword, which is similar to martial arts. Because Song Jiang was framed by Cai in Jiangzhou and was about to be beheaded, but the letter sent to Cai Jing was intercepted by Liangshan people, so he came up with a plan to forge Cai Jing's reply and let Cai cheat Song Jiang out of the city and rescue Song Jiang halfway. Xiao Rang, because of his talent and understanding with Wu Yong, was tricked into Liang by Dai Zhong sent by Wu Yong. After his family became attached to Liangshan, he was dead set on joining Liangshan. Xiao Rang is quite famous in the water margin. For example, in the three major Zhujiazhuang, it was Xiao Jean who made fake documents, which made Sun Li undercover in Zhujiazhuang successful. In Zhujiazhuang Village, it was Xiao Jean who pretended to be a county magistrate and tricked Mars and Du Xing into coming up the mountain. When Liangshan was in Juyi, Xiaorang was responsible for copying gobbledygook. His counterpart was satellites, and he was the 46th place in Liangshan. His job was to write books and adjust troops. After Liangshan was embraced, there were more expeditions from all over the country. After putting down the rebellion, Xiao Jean and the masons embedded in the army erected monuments everywhere, and the words carved were all written by Xiao Jean. Most of Xiaorang are civil servants. However, during an attack on Wang Qing, because there were not many defenders in Wanzhou, most of the soldiers were old, weak and sick. It was Xiao Jean who staged an empty plan and defeated the enemy. Before Master Cai recruited Fang La, he left Xiaorang and made him Mr. Doorman. Xiao rang's nickname is the number one scholar. Because Xiao Rang was good at imitating Su, Huang, Mi and Cai, he was called a great master at that time. There is no record of Xiao Rang in the history books, even in Yuan Zaju and early drama stories and literary works related to Water Margin. None of these works has Xiao Rang who existed earlier than Water Margin, and even the position of leader in charge of writing has never been heard of. Therefore, Xiao Rang, a master scholar, should be the author's original creation in Water Margin.
