Once upon a time, there was Tam and Cam, two sisters with different parents. The two sisters are almost the same age. Tam is the wife's daughter. Bran is the concubine. Tam's mother died when Tam was a baby. A few years later, Tam's father also died. Tam lives with her step-aunt and she is a very harsh person. Day after day, Tam had to work all the time, herding buffaloes, carrying water, cutting potatoes, picking water peas, and at night still grinding rice and pounding rice without finishing work. Meanwhile, Cam was pampered by her mother, dressed in plain white, and stayed at home all day, not doing heavy work. One day, the stepmother gave the two sisters a basket and told them to go to the field to catch shrimp and shrimp. She promised: "Whoever catches the basket full will be rewarded with a red bib." Going to the field, Tam got used to catching crabs and snails, so he was used to having a basket full of fish and shrimp in one day, while Cam was full enough to walk from one field to another, until the afternoon he still got nothing.

Seeing that Tam had caught a basket full, Cam told her: - Sister Tam, Ms. Tam! Her head was dirty, she took a deep sip, lest she scold her mother. Believing it to be true, Tam went down to the pond to wade into the deep to bathe. Cam took the opportunity to dump all of Tam's shrimp into his basket and then three legs and four legs forward. When Tam stepped up, only the basket was empty, so he sat down and cried.
