In a small, humble village lived an old farmer named Hạc. He was a man of few words, living a life of solitude with only his yellow dog for companionship. His only son had left their home long ago, seeking a better life away from the poverty that plagued them. Despite the loneliness, Hạc always held onto hope, believing in his son's return.

Hạc spent his days laboring in the fields and caring for his small garden. He never touched the earnings from the garden's harvest, saving every penny for his son's future. His life was hard, but his heart remained filled with love and hope for his son.

As time passed, Hạc's health began to decline. He could no longer work in the fields, and his once vibrant garden started to wither. The money he had saved was slowly dwindling away, yet he refused to sell his garden or use the saved money.

One day, in his frail state, Hạc realized that he was left with no other choice. With a heavy heart, he made the decision to sell his beloved yellow dog. The dog, always loyal, seemed to understand and nuzzled against Hạc one last time.

After selling his faithful companion, Hạc took the money and his savings and handed them to the village teacher. He asked the teacher to safeguard it for his son. His chest felt heavy, but he knew it was the right thing to do.

With his dog gone and his savings entrusted to the teacher, Hạc was truly alone. He survived on meager meals, often just a boiled potato or some rice. His body grew weaker, but his spirit remained unbroken, his hope for his son undiminished.

One night, in his humble home, Hạc prepared his last meal. He ate quietly, savoring each bite, his heart filled with a strange mix of sadness and satisfaction. He had given everything for his son, his love unwavering.

As the dawn broke, Hạc was found peacefully resting, having left this world behind. His sacrifice was a testament to his unconditional love for his son. The villagers mourned the loss of the humble man who had taught them the true meaning of sacrifice.

When his son finally returned, he was greeted with the news of his father's sacrifice. Overwhelmed, he vowed to honor his father's memory by living a life of kindness and humility. Hạc's sacrifice had not been in vain. His son was home.

Through Hạc's story, the village learned a profound lesson about love and sacrifice. Hạc's legacy lived on in the heart of his son and the memories of the villagers. His sacrifice was a beacon of love, illuminating the path for future generations.
