1. The poem that expresses the meaning that "people who raise silkworms and make silkworms can't release silkworms, and people who don't raise silkworms can't release silkworms" is: People wearing Luo Qi are not silkworm farmers.

2. "Those who are covered in Luo Qi are not sericulturists" comes from "Silkworm Girl" written by Song Dynasty poet Zhang Yu.

Silkworm Girl Song Zhangyu

I went to town yesterday and came back with tears in my eyes. Those who wear Luo Qi are not silkworm farmers.

3, the central idea:

Silkworm Girl is a concise allegorical poem. The poet compared the naked silkworms with silkworms wrapped in silks and satins based on what women who raised silkworms saw and felt, and profoundly exposed the unreasonable phenomenon that the working people's labor achievements were exploited and plundered in feudal society. This poem reflects the misery of working people's lives, expresses the poet's sympathy for sericulture farmers, resentment against the exploiting classes who get nothing for nothing, and accusations and lashes against the whole feudal society.
