Based upon this excerpt it seems as if Emperor Qian Long feels his culture is quite different and maybe even superior to the English culture so much so that an English envoy sent to learn about Emperor Qian Long's culture would be there in vain. This is so because he states that his culture is so different that even if the envoy is "able to acquire the rudiments," there are intricacies such as manners and customs that give the rudiments meaning, and customs and manners could never be transplanted. As such, it would be pointless to even to begin to try acquire or even learn about Emperor Qian Long's culture.
