How did agriculture and animal husbandry develop in Longshan culture period?

During the Longshan culture period, the agricultural and animal husbandry production in Sanjin area developed greatly. Although the production tools are still mainly stone tools such as stone shovels and knives, they are more abundant in variety and have developed in fineness. V-shaped stone knives and plough tools have been used.

In aquaculture, the variety of livestock has greatly increased, including pigs, chickens, cattle, dogs, sheep and so on. In terms of crops, the main crop varieties appeared in this period, mainly millet, sorghum and other gramineous crops, and they had a considerable planting scale.

Although agriculture and animal husbandry have a certain scale and development, which has changed people's living conditions to a certain extent, after all, the productivity is relatively low and the products can not fully meet people's living needs. Therefore, some collection and fishing and hunting activities are needed as a supplement.

There are dozens of plants collected, mainly collecting fruits, stems, leaves and roots of various plants. In addition, shellfish and fish and crabs in rivers and lakes are also collected.

In hunting, large and fierce mammals, such as tigers, wolves, leopards, wild boars, etc., need to rely on collective strength to capture, while small animals, such as sheep and chickens, can be captured by one person.

The meat of these animals can be eaten, the fur can keep out the cold, and the bones can be processed into hard tools, such as bone needles and bones.
