Since I was an exiled queen making medicinal herbs in a village, my sons came and prostrated themselves before me. Oh my? I wonder if something happened...

I was banished from the royal palace by my three sons and their wives. They cursed me, saying "You're too old now" and "You're a nuisance in the harem," and all I was given was a dilapidated house in a remote frontier. I grew medicinal herbs. Then one day, my sons came and prostrated themselves before me. "Mother, please tell us about your hidden fortune." A hidden fortune? I have no such thing. But isn't this the perfect opportunity to get some comeuppance?
