Lei Zu often takes everyone up the mountain to peel bark and also peel hair for processing. Soon, people in the tribe no longer need to cover their bodies with leaves. On the way up the mountain, the women picked many fruits and tasted them, either bitter or astringent. Until it was dark, I found a small white fruit in the mulberry forest, and I quickly picked it. By the time I finished picking, it was already dark, and people hurried down the mountain because they were afraid of wild animals. When they got home, they tasted these fruits and found that they couldn't stop biting, and thin silk appeared in these fruits.
After Lei Zu saw the filaments, he focused on this matter every day and went up the mountain to observe the mulberry forest for several days. Finally, he found that the white fruit was entangled by a worm spinning silk, but it was not a fruit. Lei Zu begged the Yellow Emperor to protect the mulberry forest. Later, Lei Zu began to raise this bug and named it silkworm. Lei Zu became the inventor of sericulture and silk, Lei Zu raised silkworms and Hui Ze became the whole Chinese nation.
