Why do state-owned enterprises ask about height and weight?

Because some positions have requirements for height and weight.

For example, military state-owned enterprises have requirements for weight and height. Male height should be above 162cm, and female height should be above 160cm.

Military enterprises refer to the Ministry of Electronic Industry, Aviation Industry Corporation, Aerospace Industry Corporation, Ordnance Industry Corporation, Nuclear Industry Corporation and Shipbuilding Industry Corporation. Enterprises and institutions affiliated to China Academy of Engineering Physics and Provincial Office of National Defense Industry, which undertake the tasks of military equipment and product development and production planning assigned by the state.
