Xiao Rang, a master scholar, was nicknamed because he was good at imitation?

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. 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.
