Modeling, the earliest from the English "Model" phonetic translation, mainly refers to the display of fashion products, auxiliary publicity media advertising, services to the public aesthetic needs, the expression of photographic art concepts and other related work of the professional people.

Models need to have certain conditions in terms of looks, body shape, temperament and display ability, and also have certain requirements in terms of cultural foundation, personality quality and other inner qualities.

At the same time, models can be roughly divided into two categories: print models and runway models.
