What does cross talk mean?

Crosstalk belongs to the traditional folk art of rap, and its form is to talk about learning and ridicule singing. Many friends think that singing belongs to singing or singing opera, but it is not. Singing in cross talk is mainly about singing Taiping lyrics, which can also be said to be the basic skill of learning cross talk. It was formed in the early Qing Dynasty and was popular in Beijing. Later, it was introduced into cross talk, usually before the cross talk started or during the performance. In the process of singing Taiping lyrics, you need to hold a bamboo board in your hand, and then use the linking point, stress and light tone as accompaniment to express it. Most of the words in it belong to warnings and manners.
