“零” (líng) is the Chinese character for the number zero. It represents the absence of quantity or value and is a fundamental concept in mathematics. Zero plays a crucial role in various mathematical operations, serving as the additive identity, meaning that adding zero to any number does not change its value. In addition to its mathematical significance, “零” is also used in everyday language to denote emptiness or nullity. For example, in the context of time, it can refer to midnight, or in finance, it can indicate a balance of 人民币 (RMB) that is zero.
