Regex Tester & Validator

This regex matches two consecutive pairs of Chinese numerals (零一二三四五六七八九) at the end of a line, capturing each pair as a separate group. It is useful for extracting or validating sequences like dates, codes, or counts written in Chinese characters, where two two-digit groups appear at the end of a string. The flags gm allow matching across multiple lines, with each line ending checked separately.
