Carved lacquer, also known as "Tihong," originated from lacquerware. It is a technique that uses raw lacquer as the primary material, applying it to a base to a certain thickness and then carving patterns with a knife. This method is often referred to as the art of time, representing a treasure and the essence of traditional Chinese craftsmanship. Depending on the color variations, it is categorized into Tihong (red carving), Tihei (black carving), Ticai (multicolor carving), and Tixi (rhinoceros carving).
    In 2006, carved lacquer was listed in the National Intangible Cultural Heritage Protection Catalog. In 2021, Liu Hanyin, a Chongqing native and inheritor of this craft, brought the carved lacquer technique back to Chongqing, establishing the Yu School of Lacquer Art. This art form has found its home in the Diaoyu City Scenic Area of Hechuan District, Chongqing.
