Xingjing County Zengshi Qinghong Co., Ltd. is a production demonstration protection base in Sichuan Province. Originally a state-owned sand pot factory in Xingjing County in the early 1950s, it was restructured in the 1980s and renamed as "Zeng's Qinghong Sandware Hall in Xingjing County". In 2010, it developed into the first physical sand ware limited liability company in Xingjing County, namely Zeng's Qinghong Sandware Co., Ltd. The company currently has more than 20 employees, including a comprehensive building, a boutique workshop, a regular workshop, and a raw material workshop. Since 2010, nearly a million yuan has been invested in renovating the boutique workshop into a tourism and sightseeing experimental workshop with the charm of the Han Dynasty, and building a modern production base of about 3500 square meters. After the production base is completed and put into operation, it will become a black sand expo park that integrates sand production, sales, leisure, and sightseeing.

Yingjing Sandware: a national intangible cultural heritage, a product protected by national geographical indications, the world's only existing traditional cooking technique of "Mantou kiln firing and pit restoration", inheriting the millennium love of "earth and fire".
