Yíhài

Yíhài (pinyin: yíhài) is a transliteration that may refer to multiple Chinese terms or proper nouns. In classical Chinese, 夷害 (yíhài) is a two-character compound meaning harm or damage attributed to non-Chinese peoples; the character 夷 can denote barbarian, foreign, or external threat, while 害 means harm or damage. The term appears in historical and diplomatic texts to describe external aggression or misfortune on borders; it is largely literary today and seldom used in contemporary Mandarin.

As a personal name or place name, yihai can be formed by various characters depending on the intended meaning; as a given name, it is usually two syllables chosen for auspiciousness or phonetic reason, and the reading would be yí-hài or yī-hǎi, etc., but usage varies by family. In modern contexts, such a name would typically be associated with Chinese-language naming practices rather than a widely recognized surname or geographic designation.

In modern usage, the compound yíhài is not a common everyday term; it is primarily of interest to scholars of Chinese language and history. It may appear in translations of classical works or in studies of frontier policy or diplomacy.

If you meant a specific person, place, or written form, please provide the characters or context, and a more precise article can be prepared.
