未成年人 (wèizhěnén) — refers to a minor, someone who has not yet reached adulthood, highlighting the lack of legal and social responsibilities associated with being an adult.

Imagine a 'charming' adult wearing a 'ren' (person) costume at a party, illustrating that an 成人 is someone who has grown up and is now participating fully in society. The components '成' (to become) and '人' (person) together tell the story of becoming a person or an adult.

While 成人 is typically neutral, in formal contexts, it is often used in legal documents or discussions about rights and responsibilities. Be careful not to confuse it with '青少年' (qīngshàonián), which refers to teenagers. Remember that in informal settings, you might hear more colloquial terms for adults.

As an HSK Level 5 word, 成人 connects with other vocabulary related to age, maturity, and societal roles. Students should focus on understanding its use in different contexts, such as employment, relationships, and social discussions.

In Chinese culture, the concept of adulthood is marked by specific rites of passage, such as completing education and starting a career or family. These milestones are often celebrated with family gatherings, reflecting the importance of adult responsibilities.

Learners often confuse 成人 with '小孩' (xiǎohái), meaning child. For instance, saying '他是一个成人的小孩' (He is a child adult) is incorrect; instead, use '他是一个成年人' (He is an adult).
