Once upon a time, at a small village in today’s Bac Ninh province, there was a beautiful and diligent girl born from a poor family. No matter how hard her parents worked, they could not get out of debt. The beleaguered parents had no choice but to give their daughter’s hand in marriage to a landlord’s son so as to clear their debts.
After the marriage the couple moved into a separate home and after a few years a small child was born. But every chore in the house was left for the wife as the husband was a good for nothing dolt of a man.
One day, when the child fell ill and the wife had to stay at home to take care of him, she told her husband to sell their dog at the market. Of course, the man was very reluctant as such responsibility was overwhelming for him. So, the wife repeated the instructions very clearly several times over: “Sell it at once, if someone offers eight dong or four dong now with four dong owed. If not, bring the dog home.”
