Abstract: Although H. M ovius had established his system in 1940s, the typology in Paleolithic assemblages of East and Southeast Asia remains to be solved. Movius' system based on the stone assemblages from Burma (Anyathian) and Java (Pat jtanian) consists of three new categories,chopping--tools, hand--adzes and proto--hand-axes, and two re--defined categories, choppers and scrapers. Unfortunately, this system is not a good typology to a certain extent because its categories are not " mutually exclusive" , " not overlap" and " exhaust the variability in the artifact collection" as pointed by L.G. Freeman in 1977. Many facts have shown that Movius' systemisn't very helpful to the development of the Palcolithic Archacology in East and Southeast Asia.
In vies of the materials from China, Burma, Java etc., the author of the present paper suggests that the following categories commonly used in Europe and Africa arc also suitable to East and Southeast Asia. They are chopper, handaxe, cleaver, pick, spheroid and scraper.
