Mountain silkworms, also known as celestial worms, grow in the mountains for more than 40 days. They provide high quality silk by emptying silkworm excrement and spinning silk. Until the end of their lives, silkworms keep spinning silk. They dedicate their lives to the good of people.

The ancient silk wadding technique uses underground hot springs to soak cocoons, which not only ensures clean water quality, but also saves the energy-consuming process of cocoon cooking. Throughout Weihai's history, it has been said that "where there are hot springs, there are silk wadding workshops."

Each silkworm cocoon is woven from a single piece silk, which can be up to 1,500 meters long. The silk worker needs to clear their mind and be free of distractions in order to accurately thread and pull out the silk end.

Take several silkworm cocoons, arrange the drawn silk thread ends evenly, twist them together, and rotate the ancient silk wadding machine from Jiaodong to produce clean and flawless raw silk.

There are strict rules for silk weaving. Each silk thread must cross the dent. It is common to decide which one should be picked up and which one should be put down. By following these strict rules, exquisite silk products are produced and presented to the world.
