Tianzhu (Chinese name of God)
Tianzhu (Chinese: 天主, Tīanzhǔ), meaning "Heavenly Master" or "Lord of Heaven," was the Chinese word used by the Jesuit China missions to designate God. The word first appeared in Michele Ruggieri's Chinese translation of the Decalogo, or Ten Commandements. In 1584, Ruggieri and Matteo Ricci published their first catechism, Tianzhu shilu (天主實錄, The Veritable Record of the Lord of Heaven).
"Catholicism" is most commonly rendered as Tīanzhǔ jìao (天主教, "Religion of the Lord of Heaven").
