免疫
How to Understand
免疫 refers to the body's ability to resist infection or disease, typically by developing antibodies after exposure to a pathogen. It is also used metaphorically to describe resistance to negative influences or effects.
The character 免 (miǎn) means 'to avoid' or 'to exempt,' and 疫 (yì) means 'epidemic' or 'plague.' Together, they convey the idea of protection from disease or harmful conditions, both physically and figuratively.
In daily life, 免疫 is commonly used in medical contexts, such as discussing vaccination or natural resistance. It can also appear in idioms or expressions related to resilience, like 免疫力 (immunity power). Understanding this term is essential for discussions about health, biology, and even social or emotional resistance to stress or negativity.
