Everyone in the world admires the three daughters of the Shen family for having a prosperous husband and being able to help their husbands change their lives and achieve success, but no one knows that the bottom line of this blessing is absolute devotion. When the young general recovers from illness and takes a concubine, the foolish young master adopts a concubine after recovery, and the prince of the Hou family abandons his wife in a hurry after being promoted due to fate, three backlashes come as expected - disability, relapse of madness, and paralysis, and the heartless people tear their good luck to pieces with their own hands. The three sisters, who were regarded as the "tools of prosperous husbands" in the past, finally became legends on their own, and all those who broke their promises met the tragic end they deserved.
