Lou Xinyue, a businesswoman who was forced to marry into the Hou Mansion as a concubine because her father was unjustly exiled, carries the family heirloom "Golden Thread Policy" (Secret Business Volume). She integrated the way of doing business into the thinking of the Hou family, used the account book as a knife, used people's hearts as a profit, and strategized in the deep courtyard of the Hou Mansion. Withholding moon silver? She cleverly set up a shop to make money; is the mistress suppressing her? She takes advantage of the situation to do business outside the palace; are the sisters in trouble? She backhandedly set up a trap to drain the money from the bottom of the pot. She wanted to show this high-ranking nobleman what the wealth of "exhaustive strategies" means.
