Please help explain the last two sentences of the poem. Qin carved Chinese imitation, embroidery is more innovative, iron painting silver hook is soft, and I miss it when I carved six books.

Carving the Qin dynasty to imitate the Han dynasty has made great achievements, with new flowers and embroidered forests, iron-painted silver hooks soft and healthy, and six books easy to find

This is a seven-character quatrain describing seal cutting works.

Carving Qin and imitating Han made great achievements and created a new forest of flower embroidery art. It means that the works not only have the ancient rhyme of Qin and Han dynasties, but also have their own unique innovations, which are praised by the art world.

Iron and silver hooks are soft and healthy, and six books are easy to find. Iron-painted silver hooks describe the vigorous and delicate brushwork of calligraphy. Flexibility refers to the rigidity and softness of strokes. Liu Shu refers to six construction methods of Chinese characters. People who study seal script and seal cutting must know Liu Shu to write correctly. Good thinking means clever conception. The whole sentence means that the strokes are both rigid and flexible, which shows that it conforms to the exquisite conception of the six books.
