Tongue twisters are also called urgent passwords, eating passwords and awkward passwords. It is a traditional language game in China. Because it is a simple and interesting rhyme composed of several disyllabic words or words with the same or similar pronunciation, it makes people feel strong rhythm and interesting to read.

Tongue twister is a folk language game in China, which combines words with initials, finals or tones that are easy to be confused into repeated, overlapping, flashing and awkward sentences, requiring quick pronunciation in one breath.

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.
