Born in a county town beside the Han River, Wan Ying, the host of the podcast bowuzhi.fm, never found interest in the river that flowed past her home every day. It wasn't until she returned home for a family funeral in early 2023, standing by the riverbank during a night of vigil, that she was deeply moved by the silent flow of the magnificent river. Inspired, she invites a few friends for a journey upstream the Han River, aiming to rediscover the mother river whose name has long been obscured. Han River, China's third mother river, originates between the Bashan Mountains and the Qinling Range. As it flows, it nurtures a commercial golden waterway connecting the north and south of China. This journey uncovers tales of pioneering construction, passionate departures from home, dramatic business legends, scenic views of vast farmlands, and breathtaking mountain vistas shrouded in mist.
