HukouHukou () is a system of household registration used in mainland China. The system itself is more properly called "huji" (), and has origins in ancient China; hukou is the registration of an individual in the system (kou literally means "mouth", which originates from the practise of regarding family members as "mouths to feed", similar to the phrase "per head" in English). A household registration record officially identifies a person as a permanent resident of an area and includes identifying information such as name, parents, spouse and date of birth.

Chinese jadeChinese jade refers to the jade mined or carved in China from the Neolithic onward. It is the primary hardstone of Chinese sculpture. Although deep and bright green jadeite is better known in Europe, for most of China's history, jade has come in a variety of colors and white "mutton-fat" nephrite was the most highly praised and prized. Native sources in Henan and along the Yangtze were exploited since prehistoric times and have largely been exhausted; most Chinese jade today is extracted from the northwestern province of Xinjiang.
