Chongqing - Porcelain was a Chinese invention and is so identified with China that it is still called "china" in everyday English usage. Chinese ceramics show a continuous development since pre-dynastic times and are one of the most significant forms of Chinese art and ceramics globally. Increasingly over their long history, Chinese ceramics can be classified between those made for the imperial court to use or distribute, those made for a discriminating Chinese market, and those for popular Chinese markets or for export.

On April 15, 2021, under the support and guidance of Chongqing Municipal Commission of Culture and Tourism Development and Chongqing Daily News Group, the Tourism Development Center of Chongqing Daily News Group, Chongqing News Tourism Group, and Chongqing Yuanzhi Cultural and Creative Institution jointly established the Western China Cultural and Creative Product (Industry) Development Institute and the Cultural and Creative Product Incubation and Promotion Center of Chengdu-Chongqing economic circle.

At the launching ceremony, the operator of Chongqing's Tushan Kiln project and the Qiongyao Ruins Museum of Qionglai City, Sichuan Province, signed a strategic cooperation agreement for coordinated development. In future cooperation and development, the two sides will rely on their respective advantageous cultural and tourism resources, conduct friendly exchanges and technical discussions in such aspects as overall promotion and marketing, cultural and creative industry development, tourism service improvement, and cultural brand building. They will strive to reach a consensus about cultural tourism cooperation and contribute to the Bashu Cultural Tourism Corridor construction.

At the ceremony, Li Qingquan, executive head of Qiongyao Kilns International Master Workstation at Qionglai, Sichuan, and He Zhouqiang, brand head of Tushan Kiln project in Chongqing, discussed the interactive development of cultural and creative projects in the Chengdu-Chongqing economic circle. Tushan Kiln of Nan'an District, Chongqing, and Qiongyao Kiln of Qionglai, Chengdu share the same origin in the regions of Ba and Shu. Tushan Kiln, as one of the folk kilns in the Song Dynasty of China, is a representative analogy to the Jian kiln in terms of manufacturing techniques. The products excavated from this kiln are primarily black-glazed porcelains. Being put into use in the late Song, Tushan Kiln thrived in the Southern Song Dynasty when it became widely known.

Qiongyao Kiln is the largest celadon kiln in ancient Sichuan. It was put into use in the Northern and Southern Dynasties, flourished in the late Tang Dynasty and the Five Dynasties and Ten Kingdoms period, and declined in the Song Dynasty. Being mainly distributed in Qionglai on the southwest edge of the Sichuan Basin, Qiongyao Kilns is famous for its thickest accumulation, the most abundant products, and the longest firing duration.

Coincidentally, both Qionglai and Nan'an have an ancient tea horse road. Moreover, they have the same earliest discoverer, American scholar David Crockett Graham. In 1936, he picked up the remnants of pottery in Shifangtang of Qionglai, and the Qiongyao Ruins were brought to light again. In 1938, he discovered the Tushan Kiln Site, which seemed to be coincidental but destined.

Chengdu and Chongqing have the same view of tracing to the cultural sources and creating cultural IP. After the successful reactivation of the firing technique, the two cities created Tushan Kiln and Qiongyao Kiln into their respective cultural representatives and cultural and creative IP.
