What is the philosophy in McDull's story? What's he trying to tell us?

This is a story about the growth of McDull, a pig-like child in Dajiaozui, Kowloon, from birth, to kindergarten, to middle school, to negative property. Mcdull is simple and optimistic, with average qualifications, but he has many dreams. Mai Tai is a single mother, pinning all her dreams on her son. Hope, disappointment, hope, disappointment ... all failed, but McDull created his beautiful world with his integrity and kindness. Mcdull, who was born with foresight, always hoped that he would be different in his mother's mind. When Hong Kong won the first Olympic gold medal, my mother found a coach with McDull, hoping that McDull would win glory for our country. As the days passed, McDull grew up. Although he didn't win the gold medal, he was still McDull. The unique McDull McDull is a simple and optimistic pig, and his mother pinned all her hopes and dreams on him. And McDull's story is a simple nobody with mediocre qualifications, lack of intelligence. Born at the grassroots level since childhood, he also fantasized that his fate would improve and his life would be more exciting. Therefore, McDull has many dreams, among which winning the Olympic gold medal and traveling to Maldives are his biggest dreams. He wants to be an Olympic champion, because Li Lishan, a Hong Kong sailor, was inspired by winning the Olympic gold medal. To this end, he went to Cheung Chau to study navigation technology, but as a result, he learned the "Baoshan" that had been lost for many years. This outdated stunt of local special sports is completely out of date. I want to travel to Maldives, but my mother can only take him to the mountains near Hong Kong. Even so, McDull still feels very happy. With almost stupid persistence and kindness, McDull tried to create his own beautiful life in the alternation of hope and disappointment. Watching McDull's special Christmas turkey on the screen for half a year, watching him get happiness from the ordinary, and watching him become a negative asset like many people now when he grows up and works, the audience feels more moved and sighed than laughter. This song written by the director for the grassroots in Hong Kong with animation is so in tune with their heart music, although the melody may not be beautiful. Almost everyone in this class can see their own shadow or portrayal of themselves now from McDull. Songs that can be deeply rooted in people's hearts should be the most successful songs.
