Chinese history is a bit bloodier than that. Multiple dynasties rose and fell. The nation expanded and contracted. The Mongols overran the whole country. And they were exposed to "jesus" in the 7th century but had the good sense to exterminate the cult much as the Japanese did later.

Quote:According to the stela, unearthed in the early 1600s, Christianity came to China in A.D. 635, when a Nestorian monk named Aluoben entered the ancient capital of Chang’an -- now modern-day Xi’an -- in central China. His arrival must have been the source of some excitement because the e mperor sent his minister of state to greet the guest and bring him to the palace. Although we do not know where Aluoben came from or why he visited China, some scholars believe that he arrived from Persia and was part of an important foreign delegation. Whatever the case, the Tang emperor issued an imperial edict three years later allowing Aluoben to build a monastery in Chang’an and to settle there with a handful of missionaries.
