Noun + 中
中 (zhōng) is a postposition meaning "in," "among," or "in the middle of," and it is placed after a noun to indicate being within something. It is commonly used in phrases like 声明中 (in the statement) or 过程中 (in the process). Unlike 里, which is more colloquial, 中 tends to appear in more formal or written contexts.
