Spring silkworm to the end of the dead silk,
Four sleeps cocoon into clothing.
Silkworm said: In the spring, I am still just an egg, and people sprinkle salt water on me. When the weather was warm, I came out of the egg. When I was first born, people chopped mulberry leaves for me to eat, and then I grew up and ate more, so they fed me whole.
When the sleep period came, I did not eat or move, so after two days and two nights, my skin was shedding a layer and then I became active again. Ten days after the first sleep, my sleep period came again, that is, the second sleep, so that when I reached the fourth sleep in turn, I was going to vomit silk cocoons.
At that time, my body was particularly fat and long, my stomach became transparent, and people used straw to tie me into a cluster, send me up the cluster, and say "up the mountain".
Spit on it.
Silk came out of my mouth and formed a cocoon, and people sold me to the weaving factory, weaving it into beautiful and shiny satin for people to make clothes to wear. Ever since someone created rayon, I've been devastated and not as valued as I used to be.
