Economics wizard Ai Heng unexpectedly understood the "leverage principle" of the ancestral scale beam, which coincides with the subtleties of behavioral economics. He has insight into the erratic "utility" of good and evil in people's hearts. He needs to use prospect theory to calculate gains and losses, and use anchoring effects to balance moral weights. In order to counter the rigid "moral trial", he founded the "Social Trade-off Governance Center" to integrate game theory and social choice theory into the market. Witnessed by the ancient scale, Ai Heng joined hands with the upright craftsman Lu Shi and the clever school girl Lin Miaoyan to calibrate the world's hearts among firewood, rice, oil and salt, promote the implementation of the "Convention on the Measurement of Social Good and Evil", and use the rational light of economics and the ancient wisdom of the scale to weigh and reshape a more just and humane social order.
