Sun Ya Children Growth Stories – Mysterious Wound of Prince Yueyou 

You probably haven’t seen silkworm rearing. The silkworm has four dormant cycles before the cocoon is laid, and between these four dormancy, they just keep eating. A large basket of mulberry leaves fell down, they tried to eat, thousands of silkworms eat mulberry leaves at the same time, the sound is like a heavy rain. They eat so hard, just to finish a growing process. Their efforts moved me, but they didn’t know their future, but they made me sad.
