Zhulan and Zhou Shuren thought it was a case of baby swapping, not expecting that Zhang Datie had already left the Jiang family long ago. Zhang Datie hadn't lied; this matter could be checked, as long as one knew the original family's surname and name.
After drinking a sip of tea, Zhang Datie looked at Rongchuan and said, "Back then, it was not easy to find a caravan, and one day I was late coming home from drinking. I heard a baby's wail and saw an old woman holding a basket in her hand. I initially didn't want to get involved, but the baby kept crying, and the old woman, impatient as if she feared being discovered, was about to smother the child with her hands in the basket. Having drunk too much, my head heated up, and I rushed forwards."
At this point, Zhang Datie looked at Rongchuan, the implication clear: I am also your lifesaver.
