It is necessary to continue the historical context of the Yangtze River culture and strengthen cultural self-confidence

It is necessary to protect, inherit and carry forward the Yangtze River culture, continue the historical context and strengthen cultural confidence.

The Yangtze River is the mother river that nourishes the Chinese nation, breeds a long-standing Chinese civilization and carries the profound history of Chongqing. On September 12, the 2023 Yangtze Civilization Forum with the theme of "Inheritance and Development of Yangtze Culture" kicked off. Continuing the historical context and strengthening cultural self-confidence, Chongqing is taking action.

A few simple grains of rice have a far-reaching influence behind them. In 2003, several pieces of pottery were unearthed from Dadiping site in Yunyang. A few grains of rice attached to pottery made it one of the most important archaeological discoveries in Chongqing that year. This shows that at least 5000 years ago, the ancestors in the western region of the Three Gorges began to cultivate rice artificially.
