Before the Yunsheng Group equity signing, Gu Zhiwei received a call from the hospital; an old medical record linked her to a stranger mother, and also dragged Lin Xiaoman into an identity mystery. The two girls did not let themselves be led by guesses, but instead jointly sealed the original records, completed paternity testing, and traced the entry process of the old medical record. Final evidence proved that the two's blood ties and real identities were always correct; what truly went wrong was a single line of record when the old system was digitized. They pushed the hospital to retain correction traces, and also allowed their family to re-understand boundaries and trust.
