silkworm
蚕 centers on the silkworm, the insect cultivated for silk production.
蚕 combines 天 (heaven) and 虫 (insect), likely reflecting the silkworm's economic importance as a 'heavenly insect' in ancient China.
The top 天 (heaven) and bottom 虫 (insect) together suggest a special insect from heaven: the silkworm.
For サン, imagine the sun (サン) shining down on the heavenly silkworm, helping it spin silk.
