Number + Noun (without measure word)
In Chinese, when a noun is preceded by a numeral that represents a specific quantity in context (such as percentages or large round numbers), the measure word can sometimes be omitted. This typically occurs with percentages, approximate figures, or when the noun phrase functions as a unit of measurement. This pattern is common in news and formal writing.
