Why might the Dragon King view softskins as being inferior in the book Dragonwings?

The Dragon King might view softskins (non-Chinese people) as inferior in "Dragonwings" due to prejudices and stereotypes associated with immigrants and outsiders. He may also feel a sense of superiority based on his own cultural background and beliefs. Additionally, the Dragon King's perception of softskins as inferior could stem from fear of the unknown or competition for resources.
