First, the ancient natural environment of Shaoxing

The ancient natural environment of Shaoxing is divided into two parts, one in the south of the mountain and the other in the north of the mountain, bounded by the flat water of Huiji Mountain. Shannan is a mountainous area where the ancients lived in groups. To the north of the mountain is a swamp area, and the sea water rises from time to time until it is flat.

Shaoxing people dug peat from the dry riverbed of last century 1967; In the days of studying in Dazhai, young intellectuals dug peat from more than one meter underground while digging graves for land reclamation. When these peats were first dug up, they were piles of thatch, leaves and branches, which turned yellow in the dark. As soon as the sun shines, these thatched leaves and branches turn into black peat, which is an unrecorded archaeology in Shaoxing Plain. The masters who are still drilling wells today tell you a story that Shaoxing often encounters muddy coal seams when drilling wells. How is peat formed? I thought it was thatched grass and leaves of small trees growing on ancient beaches. The sea often rushes to the beach, and the thatch grows tenaciously. When the Qiantang River rises, the seawater is mixed with sediment, which washes a lot of sediment onto the beach, and of course, some inlets are left on these beaches. These inlets later became Jianhu, Baitayang and other lakes, which were connected with Wanshui River. The ancients lived in the mountains. When the plain was no longer a world of water, the ancients gradually immigrated to the plain to live. The cultural sites of fairy mountain and Fenghuangdun in Ma 'anshan are about 5,000 years ago. Hemudu culture, which originally belonged to Shaoxing, shows that Shaoxing ancestors immigrated to the plain five or six thousand years ago.

Ancient Shaoxing was located in the tropics, with abundant precipitation and warm and humid climate, which was very suitable for the growth of many kinds of animals and plants. The southern hills are dense forests, towering ancient trees and shady trees, which are a paradise for wild animals. In the northern water network zone, swamps are everywhere, rivers and lakes crisscross, and fish resources are very rich. The soil in the central valley basin is loose and fertile, which is beneficial to the development of planting.
