After her father passed away, Liu Yulan, who had taken care of him for ten years, was pressured by her older brother and sister-in-law on the very day of his seventh-day memorial to sign a waiver of inheritance. Faced with the prejudice that "married-out daughters should not get a share of the family property," she did not simply back down, but instead used recordings, bills, and evidence to defend her dignity and rights. As the will left behind by her father was made public, the truth gradually came to light, and she also learned to use the law to hold on to the justice she deserved. After experiencing the test of family affection, Liu Yulan rediscovered the courage to live. The story conveys the positive energy of filial piety, respect for women, and defending rights according to the law; true family affection lies not only in blood ties, but even more in responsibility, understanding, and commitment.
