U+303A "〺" Hangzhou Numeral Thirty Unicode Character
Unicode Version 17.0
〺
U+303A "〺" Hangzhou Numeral Thirty is a rarely used symbol from the CJK Symbols and Punctuation block, representing the number thirty in the traditional Hangzhou (or Suzhou) numeral system, a decimal notation historically employed in China for financial and commercial accounting to prevent fraud. Unlike the common Chinese numeric characters, these Suzhou numerals are derived from ancient rod numerals and are typically written vertically in accounting ledgers, where "〺" specifically signifies three tens. Its inclusion in Unicode preserves a historical counting method that was once widespread in East Asian trade but has since largely been replaced by Arabic numerals and standard Chinese characters.
