The classical Chinese novel ''[[Dream of the Red Chamber]]'' or ''Dream of the Red Mansion'' (''Hong2 Lou2 Meng4'') by Cao2 Xue3 Qin2 and Gao E (~1750); with some errors and omissions.  Chinese characters were mapped 1:1 from GB (Guo Biao) to pinyn with tone marks and disambiguating suffixes, e.g. 'zuo4', 'zuo4.1', 'zuo4.2', so as to distinguish characters with the same pinyin.  Each character is treated as a separate word.
