When she was about to die, the wooden hairpin on her head appeared and she was reborn back to the time when the news of her second son's death came. After his rebirth, Lu Minggui saw the true face of his eldest son's family and determined to protect his second daughter-in-law Shen Juye, his granddaughter Manman and his youngest son Song Xiaodong.
