In Asia, there are three literary circles: the Han literature circle in East Asia, the Indian literature circle in South Asia and Southeast Asia, the Islamic literature circle in West Asia and Mideast, which are somewhat independent from each other but correlate and overlap as well. These three circles, propelled by the religious dissemination, kept expanding and disseminating from their original centers, and eventually overlapped on the edges and merged into one piece: Asian literary region. While European literary region has a structure of “y”, which developed from the same origin: the join of Ancient Greek and Hebrew literature, the Asian literary region, so to speak, seems to be three overlapped circles.
