Bible translations into Chinese include translations of the whole or parts of the Bible into any of the levels and varieties of the Chinese language. The first translations may have been made as early as the 7th century AD, but the first printed translations appeared only in the nineteenth century. Progress on a modern translation was encumbered by denominational rivalries, theological clashes, linguistic disputes, and practical challenges at least until the publication of the Protestant Chinese Union Version in 1919, which became the basis of standard versions in use today.
