During this time, she encounters repeated harassment from the Duke's estate and accidentally meets the fallen Prince Ping, Xiao Linyuan. Moving step by step, Meng Wantang defeats her opponents, builds the prosperous Wantang Street, reaps success in both career and love, and lives out her life as the capital's richest woman.
