Dissemination:

Buddhism was originally popular only in the Ganges valley in central India. During the Peacock Dynasty, King Ashoka regarded Buddhism as the state religion, extensively built stupas, carved decrees and doctrines on cliffs and stone pillars, and spread to many places in the South Asian subcontinent. At the same time, teachers were sent to neighboring countries to preach, starting from Myanmar in the east, Sri Lanka in the south and Syria and Egypt in the west, making Buddhism gradually become a world religion.

Buddhism spread to all parts of Asia, which can be roughly divided into two routes: first from the south to Sri Lanka, and then from Sri Lanka to Myanmar, Thailand, Cambodia and Laos. It spread northward to China via Pamirs, and then from China to Korea, Japan, Vietnam and other countries.
