The First Series of Standardized Forms of Words with Non-standardized Variant Forms (Chinese: 第一批异形词整理表) published on December 19, 2001 and officially implemented on March 31, 2002, is a Standard Chinese style guide published in China. It contains 338 Standard Chinese words that have variant written forms (i.e. where the same word may be written with one or more different Chinese characters with the same pronunciation, referred to as "异形词", translated into English in the official publication as "variant forms of the same word"). In the First Series, one of the variant written forms for each word was selected as the recommended standard form.
