别再说中国是大 | Mandarin Grammar: Distinguishing Shi and Hen in Sentence Structure

In Mandarin Chinese, the English verb "to be" (am, is, are) is translated differently depending on whether you are defining a subject or describing it. There are two common words used for this purpose: shì (是) and hěn (很).Shì (是) is used for definitions and occurs when a sentence ends with an object or a noun. For example, when saying "He is Chinese," the sentence literally translates to "He is China person". Because "person" is a noun, shì is the correct link. Definitions typically represent fixed categories that do not have "levels"—for instance, a person generally is or is not Chinese, rather than being "very Chinese". Other examples where shì is used include identifying someone as a "beautiful girl" or a "handsome guy," because the sentence concludes with the nouns "girl" or "guy".Hěn (很) is used for descriptions when a sentence ends with an adjective. The standard grammatical pattern for these sentences is Subject + hěn + Adjective. For instance, to say "China is big," "He is good," or "I am happy," you must use hěn as the linking word. Unlike definitions, descriptions involve various levels of intensity, such as being "big," "very big," or "extremely big".While many dictionaries translate hěn as "very," in these basic sentence structures, it often functions simply as a link word between the subject and the adjective rather than adding emphasis. If you wish to express the "real very" or a higher level of intensity, you replace hěn with a more emphatic word such as fēicháng (非常). For example, while "I am hungry" uses hěn as the link, saying "I am very hungry" requires replacing hěn with fēicháng.To determine which word to use, look at how the sentence ends: if it ends with a noun or object, use shì; if it ends with an adjective, use hěn.
