Model, originally derived from the transliteration of the English "Model", mainly refers to professionals who are responsible for displaying fashion products, assisting in media advertising, serving the aesthetic needs of the public, and expressing the concept of photography art.

Models need to have certain conditions in terms of appearance, figure, temperament and display ability, as well as certain requirements in terms of cultural foundation and personality quality. At the same time, models can be roughly divided into two categories: flat models and runway models.

Height is the basic condition that a T-stage model must have. Usually, it is not less than 170cm, and the requirements for body proportions are also stricter. In terms of appearance, the pursuit of "personality" and "characteristics" is not "beautiful". Plane models pay the most attention to appearance, followed by body proportions, and there are basically no standard requirements for height.
