What kind of farm tool is Ray?

Lei is a wooden crank farm tool, with a sharp Mu Cha at the lower end for stabbing the ground, and a small bar at the upper end, where you can tread when plowing.

This paper examines Xu Zhongshu's "class examination" from the word "class" and "eye" (the first word of class, that is, the word "one") in Oracle Bone Inscriptions Hezhong, and holds that "class is a branch farm tool and class is a stick farm tool".

Rem's remains were found in archaeological excavations. Lei's labor traces were found on the walls of Miaodigou, caves in the early Longshan culture and caves in Yinxu. Thunder is indeed the beginning, and the width between the two "arthralgia" is four to eight centimeters, and the diameter is four to seven centimeters, which is very consistent with the ancient literature records.

The Significance of Reddy's Invention

With thunder, there is a real "agriculture", and there is farming and sowing agriculture. Yan Di tribes began to sow millet on a large scale and domesticated some wild plants as crops, such as millet, rice (wheat), barley, rice and hemp. Later generations collectively referred to these crops as "five grains" or "hundred grains", leaving many beautiful legends of "Shennong making five grains".

In fact, the invention and improvement of production tools and the domestication of wild animals and plants have been gradually realized by human beings in long-term production practice. Later generations attributed these achievements to Emperor Yan, expressing people's respect for him and nostalgia for their ancestors.

In the process of tribal migration and expansion, farming tools and techniques spread rapidly to the vast basins of the Yellow River and the Yangtze River, and gradually formed the farming custom of planting dry food in the north and rice in the south.

It is this simple thunder that excavated the gurgling spring flow of farming culture in the vast wasteland. Therefore, Yan Di tribe became the representative of advanced productive forces in Yan Di era. Emperor Yan of Shennong, the "pioneer", is the ancestor of farming culture in China.
