In the way of expression, "speaking" dominates "learning", "teasing" and "singing"; In content characteristics, "teasing" restricts "speaking", "learning" and "singing". On this basis, some people divide cross talk jokes into two categories: telling jokes and learning to sing, classifying telling jokes as language skills and learning to sing as imitation performances.

In fact, these two categories are not the same, and "learning to sing" is still attached to "telling jokes". "Learning to sing" can't be regarded as "Liu Xiahui" of cross talk if it doesn't make jokes. "Say" and "tease" can't be "opponents", but I have you, you have me, and they are mutually causal. If Shuo has no distinctive comedy style, it is a storytelling or story. On the other hand, if "teasing" is not expressed by "talking", it can only be a gag in comedy, and it is still not the art of cross talk.
