In 1981, Panpan, who had been mistakenly switched with another child as a baby, was cruelly abandoned by her harsh adoptive parents. With red birthmarks on her cheeks and a heart full of fear, she returned to her biological family, the Chen family. Fortunately, Panpan received overwhelming love and affection from the Chens, gradually shedding her former timidity. With her pure and kind heart, she grew up toward the sunshine, gently protected by her parents and dearly cherished by her five older brothers. Their unconditional love healed the wounds of her past, helping her regain her confidence and sense of security.
