During the reign of Emperor Qianlong of the Qing Dynasty, the weaving technology of rush hats from Gulin, Ningbo, was introduced to Changhe, and gradually became the main sideline of local women. It became popular a few years later. In the fourth year of the Republic of China (1915 AD), it won the third prize at the Panama World Export Exhibition. In 1917, it was honored as the hometown of straw weaving by the Zhejiang Provincial Government. In 1923, the weaving of straw hats with golden silk grass was successfully introduced from the Philippines. Since then, it has become more prosperous, and the weaving technology has been further improved. The folk proverb says: "Yaobei has three treasures, cotton and white salt grass cool hats" and "There are no idle women in the ten-mile long street, and every family is a hat weaver." There were more than 200 hat shops of all sizes, and more than 100 star vendors. In 1934, the output reached 2.1 million hats, accounting for one-third of the total exports of Ningbo Customs. After the founding of the People's Republic of China, the "State-owned Golden Silk Straw Hat Factory" was established. In 1983, it won the Quality Product Award of the Ministry of Commerce. Its products are exported to more than 80 countries and regions, becoming a world-class and famous export handicraft in my country. The so-called golden grass is the stem extracted from wild palm leaves, which is processed after rinsing, drying, softening, and selection. The traditional weaving process includes: picking grass, tying grass, lifting the top, weaving hats, cutting hats, washing hats, rinsing hats, rinsing, drying hats, grinding hats, ironing hats, turning hats, loading hats, and shipping. The craft technology has also developed from a single core weaving method to double cores, three cores, empty cores, overlapping cores, and braided cores. The weaving raw materials have developed from a single golden grass to more than 10 kinds of Nante grass, salt grass, ox grass, straw cores, corn husks, and paper grass. The weaving varieties have also expanded to more than 1,000 styles such as various baskets, handbags, carpets, door curtains, toys, gift bags (boxes), mats, etc. At present, a company has created a set of "bleaching, grinding, steaming, baking, and ironing" assembly line equipment, with about 10,000 employees (including amateurs), and the number of manual weaving has decreased, while the amount of mechanical weaving has increased. The current inheritance situation is still good.
