Buddhism reaches China gradually along the Silk Road, entering as the Han Empire's own westward expansion put it in direct contact with Central Asian Buddhist communities, well before any single dramatic conversion carries the story. By the second century CE named monk translators, Lokaksema from Gandhara among the earliest, and the Parthians An Shigao and An Xuan among them, were already rendering Buddhist sutras into Chinese at Luoyang.
That translation work is the beginning of an enormous ongoing enterprise, the process through which a foreign religion became genuinely Chinese, read in its own language rather than only carried by foreign speakers. The traditional account crediting Emperor Ming's dream and a resulting embassy to India, conventionally dated to 67 CE, is a later legendary elaboration rather than an independently verifiable event, and this atlas records the translators' own documented work as the real beginning instead.
What changed for Buddhism's spread is access to an entire new textual language and, through it, to Chinese readers directly. From Luoyang's own translation circle the tradition would go on to reach Korea and Japan in turn, carried each time by monks moving between courts rather than by trade alone.
