Tongue twisters can be traced back to the era of the Yellow Emperor more than 5,000 years ago. Fortunately, "Playing Songs" preserved in ancient books is said to have been written by the Yellow Emperor.

According to textual research, this is a ballad close to the original form, in which the basic component of tongue twisters-disyllabic rhyming words have long existed. Presumably, tongue twisters sprouted in the spoken language of working people in China before the appearance of words.

Because of the gradual improvement of tongue twister, it has spread among the people, and some scholars close to the lower class have begun to pay attention to this popular literary form.
