A few scenes about local mixed children touched me. The first one is Nullah standing on the edge of the cliff, he is not worried when he saw the head of the cow. But when he used his grandfather to teach his song and let the cow away, he had his teers in his eyes. The second is that Nullah was taken away by force. He said to Sarah, "I will guide you with my song, you will find me, I believe you!" Finally, Nullah took off his coat, and his grandfather left with joy and firmness. The use of Nullah is opportunistic. The last sentence of the story "I finally understand why grandpa can tell stories is important, because it will let us remember those who love me forever." Although the film will end, our heart is slowly warming
