Silkworm rearing belongs to science education and life science.

From hatching to spinning and cocoon formation, it takes about 6 to 9 days for a silkworm to molt. After four dormancy and molting, it takes 30 days to grow to 6 to 7 cm, and the weight increases by about 10 thousand times before spinning. The teacher said that a silkworm spins silk 1.5 kilometers long, and turning an arm into a jade refers to silk fabrics. Later, I learned that China was the first country to raise silkworms and spin silk. In ancient times, there were legends about Fuxi sericulture and Leizu sericulture. Silkworm and Silk Road are symbols of China civilization.
