Furthermore, its dissemination has led to the emergence of numerous Chinese vulgar characters incorporating the wen (文) components. According to the unearthed literature, the inherited literature and the extraterritorial literature, the wen (文) components exhibits more than ten functions, categorized into three types: symbolic function, combined symbolic and ideographic function, and ideographic function.
