危害

The Chinese word 危害 (wēihài) is composed of two characters: 危 (wēi) and 害 (hài). The character 危 originally meant "cliff" or "precipice", and later extended to mean "dangerous" or "perilous". The character 害 originally meant "to harm" or "to injure", and later extended to mean "evil" or "calamity". Thus, the compound word 危害 means "to endanger" or "to cause harm".The word 危害 is often used in a negative sense, to describe something that is harmful or dangerous. For example, we can say 危害环境 (wēihài huánjìng) to mean "to harm the environment", or 危害健康 (wēihài jiànkāng) to mean "to endanger one's health". However, the word 危害 can also be used in a positive sense, to describe something that is beneficial or helpful. For example, we can say 危害社会 (wēihài shèhuì) to mean "to benefit society", or 危害人民 (wēihài rénmín) to mean "to help the people".The word 危害 is a common word in Chinese, and it is used in a variety of contexts. It is important to understand the meaning of this word in order to communicate effectively in Chinese.
