ORD-PVG-ORD direct turn, leaving ORD at 9:50 am (Dec. 3) and returning at 4:10 pm (Dec. 4). There is 2:45 for transfer. If you do not have a China visa, it costs $140 for ten years ($14 a year) at Chinese Consulate in Chicago. You can get it before your trip if you go to consulate tomorrow, I guess. Good luck.
