Xuanyang Post in northern Henan, a thousand-year post road stretches across the Central Plains, the fragrance of cakes surrounds the beacon fire, and the fireworks reflect the rise and fall. A side of Yi Dao cake embodies the gentle livelihood of the ancient Yi family and is branded with the war smoke of the troubled times. From the heritage of the Shang and Zhou dynasties to the hustle and bustle of the Ming and Qing dynasties, from the Chu-Han turmoil to the changes in zoning, legends about ancient monuments are hidden on the stone road, and the smoke from the post house wraps up the joys and sorrows of the people who keep the post. When the war broke out, the hands that kneaded and baked the dough never stopped; in the vicissitudes of the post road, the heart of sticking to the homeland never wavered. The fragrance of cakes is the bones, and the flames of the beacon are the soul. In the intertwining of history and people's hearts, a long song of the years of the ancient post in the Central Plains is unfolded, describing the sincerity and tenacity of the little people in the ups and downs.
