Where do East Asian and south Asian culture diverge the most?

I know some things are in common like education and valuing people in your life but where do they split? What are some of the main differences?

Some I think are religion, social issues (little to no @rr@ng€d m@rri@g€$ in East Asia) them mixing with Whites and others much more often than Desis do, and p@r€nting being slightly stricter in south Asian vs East Asian culture

Also both view fair skin as good but Desis are more skeptical to mix with Whites, East Asians and others
