If the 'little man' in the story faces challenges and overcomes them, the moral might be about perseverance. It could show that no matter how small or insignificant one may seem, with determination and hard work, one can achieve great things. Another possible moral could be about kindness. If the little man is kind to others and gets rewarded for it, then it teaches the value of being good to those around you.
I'm not sure exactly who the cast members are without further research. But it might include actors who can portray Little Richard and other relevant characters in his story.
Ruyi Langjun was a character from an ancient myth. He was a kind, smart, and brave young man, and was deeply loved by the villagers. One day, he met an old Taoist priest on the mountain.
