When the boy won the top prize: He returned home with
emperor's extra rewards.
When the two families united: Lady Cao learned the emperor
verified the new G2 pack and praised her as an excellent
child care worker.
When lady Cao revealed her jade cicada: The boy realised
she was not a volunteer child career and he was not an unaligned
When lady Cao died on the boy's wedding to the girl: A life
destroyed, a heart broken and a soul in grievance.
A lesson to the heads of a family, a community or a state:
If you have a courage to sign an unfair agreement with your
pen, your words or your jade cicada, you ought to have a
courage to renounce it. Or you deserve to be impeached from
the position in whatever the domain you reside.
