钅[钒] is used as a radical, which is called "jinzibang". Many simplified characters evolved from cursive scripts. For example, 讠[訁], 饣[壠], 纺[糹], and 酅[釒] are written in cursive script in the form next to the word "酒" today, so characters with "釒" next to them are all written in simplified Chinese. "钅" came to express it.
The words next to the word "钅金" are:
1. Needle (Pinyin: zhēn), a common standard Chinese character (commonly used character) at the first level of Chinese. The variant character for needle is written as "needle", which was probably produced during the Warring States Period; the word "needle" was produced after the Han Dynasty. The original meaning of a needle refers to a tool used for sewing clothes. Its shape is elongated and has a sharp head. Needles are characterized by being pointed and slender. Other things with this characteristic can also be called needles, such as pine needles, compasses, etc.
