C Jerry is talking to Cindy about Chinese fantasy stories. Read their conversation and order the events. Write the correct numbers on the blanks.
Cindy: Jerry, do you like Chinese fantasy stories?
Jerry: Of course! I really like the story of Gong Gong.
Cindy: He was a water god, right?
Jerry: Yes, that's right. One day, Gong Gong got into a big fight with a fire god, Zhu Rong. Gong Gong lost the fight and got very angry.
Cindy: What did he do?
Jerry: He knocked his head against Mount Buzhou. This was terrible for humans because Mount Buzhou helped hold up the sky. When Gong Gong hit the mountain, it fell apart. Rivers flooded and forests burnt. Part of the sky fell down too. It left a hole in the sky.
Cindy: That must be why Nuwa had to fix the sky! Do you know the story of Nuwa?
Jerry: A little.
Cindy: Nuwa was a powerful goddess. When the sky broke, she saw that many humans were afraid. Since she made and loved humans, she decided to fix the sky.
Jerry: How did she do it?
Cindy: First, she collected many five-coloured stones. She burnt the stones and mixed them together into a large piece to fix the hole in the sky. Then, she used a big turtle's four legs to hold up the sky.
Jerry: What an amazing story!
