Hainan Island was advantaged for the rich ecological environmental resources, and the fishing and hunting economic activities were very and rich and colorful. The collecting activities originated along the seashores, and then extended into mesas and hummocks. The terrestrial collecting developed from ground into underground, from potherb, leaf and fruit collecting into earthnut collecting, and the aquatic collecting from slow animals empty-handed collecting at the shallow sea into tooled halieutics. As with the long coastline, wide maritime space and abundant sea-born mollusks in the island, tooled halieutics developed rather later. Hunting played a very important role in the economy of the aboriginal in the island, their hunting technology was gradually improved. Because of different geographical conditions, the inhabitants in the middle of the mountainous area gave priority to collecting and hunting and their halieutics was not advanced, while in the littoral they gave priority to halieutics and collecting but their hunting lagged behind. The island was advantaged for the abundant natural resources and sparsely populated, the inhabitants relied on the natural resources and their collecting, fishing and hunting had lasted very long, therefore, their agriculture in the history was not yet mature.
