Crosstalk master Jiang Kun and sketch master Cai Ming.
Guo Yang and Guo Liang are some special comedians. They are special because they are one of the few twins on the domestic comedy stage. On the other hand, Guo Yang and Guo Liang not only speak crosstalk but also perform sketches, and have their own masters in both fields. In May 2016, Jiang Kun took them to participate in the large-scale performance of "Jiang Kun "Speaks" Crosstalk" and accepted them as his apprentices at the end of the curtain call. Jiang Kun already had a pair of twin apprentices, Liu Quanli and Liu Quanhe. Later, Guo Yang and Guo Liang considered that there were many opportunities to appear in sketches, so they also wanted to learn systematically, so they became apprentices to Cai Ming, who had led them on many shows.
