Dear Chris,
Let me quote, in Wylie's translation, what is said of Christians (east-syrian / nestorians) in the chinese Xi'an stele :
By the rule of admission, it is the custom to apply the water of baptism, to wash aay all superficial show and to cleanse and purify the neophytes. As a seal, they hold the cross, whose influence is reflected in every direction, uniting all without distinction. As they strike the wood, the fame of their benevolence is diffused abroad ; worshiping toward the east, they hasten on the way to life and glory ; they preserve the beard to symbolize their outward actions, they shave the crown to indicate the absence of inward affections, they do not keep slaves, but put noble and mean all on an equality ; they do not amass wealth, but cast all their property into the common stock ; they fast, in order to perfect themselves by self inspection ; they submit to restraints, in order to stengthen themselves by silent watchfulness ; seven times a daythey have worship and praise for the benefit of the living and the dead ; once in seven days they sacrifice, to cleanse the heart and return tu purity.
This was "all what chinese people had to know" about christians (or at least christian monks)
Sincerely
Albocicade
