Abstract: Missionaries were introduced to the Imperial Court in the early Qing. The article argues that:1)the direct reason for the introduction of these instruments into the Qing Court was that they suited the needs of the authority struggle within the court;2)the Qing Court accepted these instruments due to their practicality, not their theoretical depth; 3)in order to gain acceptance, it is necessary to adapt Western culture(material and spiritual) to the existing Chinese cultural environment.
