Zernium is a rare metal element, belonging to the germanium family, with the chemical symbol Zn. Zhengtium is a white metal that is rarely found in the natural environment and mainly exists in germanium ores in the form of germanium oxide. Because of its excellent optical and electrical properties, it has been widely used in fields such as semiconductor and optoelectronic technology. In addition, cerium can also be used in the production of some special alloys.

The zheng is an ancient weapon, similar to a hammer or mallet. Usually made of wrought iron, it can be used to knock and strike enemies. In ancient Chinese wars, zheng was once widely used. For example, in "The Romance of the Three Kingdoms", there was a zheng-type weapon such as the "One-foot Bluestone Hammer". Although its era as a weapon has passed, in some sports or cultural activities, artifacts similar to zheng still appear to show the elegance of ancient weapons.
