Being a woman, I expect life in ancient China would have been filled with constant labor and fear of dishonor and punishment. Unless I was one of a handful of beautiful, wealthy, or influential women, I expect that I would spend my life unnamed, uneducated, and in the servitude of my husband, his family, and my male children. Although raising a family is one of my greatest joys, that joy comes somewhat from having the choice to do so.
Probably not very well. The huge mass of people in ancient China were poor and powerless. Unless I were one of the very few rich elites, my life would have been one of endless hard physical work with very little in the way of rewards. The average person in ancient China had a very hard life and there's no reason to assume I'd be different.
I assume you mean what was society and culture like in ancient China. There was class distinction, The upper classes lived in large mansions made from pounded earth, a process by which soil was packed and pounded so tightly that it had the strength of bricks. They had a diet of fish, pork, poultry, even mutton, and had tools, weapons and ornaments made of bronze, which was prized, but possessed only by the upper class. Peasants lived in sub-terranean dwellings usually three feet or more below the surface made with thatched roofs. Their diet consisted of porridges made of rice or millet. They were did not own their own land, but worked the fields of the nobility, and were required to pay a portion of their harvest as rent.
A very small middle class of jewelers, silk merchants, and embroiderers. They lived in cities and worked primarily for the upper class, as the peasants couldn't afford them.
