In Bianjing in the Northern Song Dynasty, the Shen family's tea business was extremely prosperous.
The main wife Lin is dignified and ruthless, while the concubine Zhou is forbearing and plotting. The newly widowed Liu spent three years investigating and finally found the truth behind her husband's fall from a horse - the severed girdle was connected to the tea shop's secret expenditure of 100,000 yuan a year, to the Imperial City Department's major corruption case, and to the lives of everyone in the Shen family.
The legitimate son Shen Ye was originally a playboy, but he grew up overnight when the family was in crisis; the concubine Shen Kai went to Suzhou to use his fame to rewrite the fate of his concubine; the jade slave who sang the song did not dare to love him for fear that she would not be able to take it back if she was moved; the new aunt Xue Siniang did not know how to fight, and could only embroider her own way of life stitch by stitch.
When the guards of Kaifeng Mansion knocked on the door of Shen's house, when everyone thought that the Shen family was doomed, the woman named Liu Xiyin came back——
"I promised him that I would protect the Shen family for him."
