Geographer Shen Tuo accidentally traveled back in time to the third year of Zhenghe in the Northern Song Dynasty. When he woke up by the Bian River, he had a mouthful of soil in his mouth.
This was not the country he was familiar with—no GPS, no roads, no data to look up.
He can only walk on two legs, see with his eyes and remember with his heart.
In a small inn in Yingtian Mansion, he met Sun Erniang, who was illiterate, Lin Yuan, a mysterious imperial student who knew how to shake hands, Zhou Yun, a wealthy lady from a declining family, and Sun, a veteran with a lame leg. This group of people got together and began a journey around the world.
Along the way, they walked through Bianshui, Jianghuai, Jiangnan, and Qingxi, and met an old man who had been selling tofu all his life, an old woman who collected mulberry leaves and raised silkworms, a beggar who divided half an oilcloth in the Chenghuang Temple, and the owner of the lacquer garden who asked "How is the world going?" They laughed, cried, and toasted a glass of wine "To Carrots" by the fire on a winter night.
Because they know that - fourteen years later, the Jingkang Revolution is coming, and this era will eventually be crushed by iron hoofs.
They are unable to change history. They can only measure mountains and rivers with their footsteps and remember their old friends with pen and ink.
