The agricultural period embodies the concept of natural balance and achieves harmonious coexistence between humans and nature. During the period dominated by agriculture, the production and lifestyle of ancestral villages were relatively simple, with minimal damage to the natural environment. The basic material needs and outdated production methods mean that people rely more on natural resources such as wind and water energy, rather than excessive consumption or environmental damage. Therefore, the carbon emissions generated by this lifestyle are relatively low, and the community can rely on its natural carbon sink capacity to maintain overall balance. The ancient windmill evolved from sails and had 6 to 8 sets of canopies resembling sailboats, distributed around a vertical axis. When the wind blows, it rotates around the axis like a revolving lantern, known as the "revolving lantern style windmill". This type of windmill, due to its low efficiency, has gradually been replaced by wooden canopy windmills and other windmills with horizontal rotating shafts, such as "vertical windmills" and "automatic rotor windmills". Ancient windmills were controlled by ropes or barriers to sail.
