Proverbs:

Proverbs are one of the idioms, which refer to established, widely popular and concise sentences. Broadly speaking, common sayings include proverbs, two-part allegorical sayings, idioms and commonly used oral idioms, but they do not include dialects, common sayings, idioms in written language, or famous sayings and epigrams in famous works.

In a narrow sense, common sayings are one of the genres with their own characteristics, which are different from proverbs and two-part allegorical sayings, but some common sayings are in between.
