What does "Heidi and Grandpa", which exploded among children, reflect the children's ideas?

Orphan Heidi was sent to the Alps by her aunt Dieti to live with her grandfather, who lived alone in the mountains far from the town. The lively Heidi is here, not only harvesting the friendship of Peter the sheep and the affection of the lonely grandfather, but also mingling with Peter's family under the mountain. One day, Heidi and Peter were herding sheep in the mountains, when her aunt suddenly appeared and tricked Heidi into selling her to the Zessermann family in Frankfurt. Since then, Heidi has become miss Clara's companion. Clara lost her mother at an early age, fell ill and could no longer stand, and could only be trapped in a mansion with a wheelchair. Rarely returning home for many years, the lonely Clara used Heidi as a lifesaver. But Heidi eventually left because she missed her grandfather, and Clara went to visit her, which made another wave.

This beautiful and warm film reflects that children are yearning for love and warmth, every child is an angel, parents should give them care, and the growth of children needs the love of their families.
