Cultures are different everywhere. Comparing the Chinese culture to America is like comparing water to a rock; there are to many differences all the way back to when we are children being raised to adulthood and beyond. To some cultures, altering their bodies severely is a thing of beauty and power, while others look at it believe they have a medical condition or consider it 'ugly'.
So yes, children (at least most) consider the Qilin adorable, good luck, and worthy of their adoration, because they have been raised as have every other generation before them, that the Qilin, despite their angry looks, are protectors of life and good fortune. Just as Dragons are not just considered 'fire-breathing monsters' in China, but guardians and protectors that represent justice and good fortune.
Or how fire represents cleansing evil and the power of good and justice, whereas in America and the like, it's considered evil and destructive. The differences are nearly polar opposite among some cultures, and that's all there is to it.
