What about the full text of snail and earthworm?

Snails crawl slowly at the foot of the wall. The earthworm saw it and asked, "Brother Snail, where are you going?" "I want to go to the top of the wall." Said the snail. Earthworms couldn't help laughing: "Hum! Do you want to go to the top of the Great Wall? Stop daydreaming! You have to know how slow you climb! " The snail ignored it and continued to climb the wall. The earthworm thought the snail was stupid, smiled and got into the mud to sleep. The earthworm woke up, got out of the mud and saw that there was no snail left. It turns out that the snail has climbed to the top of the wall.
