Chinese characters
The use of such contractions is as old as Chinese characters themselves, and they have frequently been found in religious or ritual use. In the Oracle Bone script, personal names, ritual items, and even phrases such as Shou You (You ) shou you "receive blessings" are commonly contracted into single characters. A dramatic example is that in medieval manuscripts Pu Sa  pusa "bodhisattva" (simplified: Pu Sa ) is sometimes written with a single character formed of a 2x2 grid of four Shi  (derived from the grass radical over two Shi ). However, for the sake of consistency and standardization, the CPC seeks to limit the use of such polysyllabic characters in public writing to ensure that every character only has one syllable.
