This year marks the 50th anniversary of the discovery of the Qingdun Ruins in Qingdun village, Hai'an county, Nantong, East China's Jiangsu province.

The ruins are the most well-preserved site of the Neolithic Age – defined in China as between 10,000 to 4,000 years ago – in the eastern part of the Jianghuai Plain.

To commemorate the discovery of the Qingdun Ruins, Hai'an authorities will organize a series of activities and give full play to the ruins' contemporary value, attracting more people to learn about, enter, and explore the ruins.

Hai'an Museum plans to issue a set of stamp folders themed on the 50th anniversary of the discovery of the Qingdun Ruins. The folders will be designed following the relics unearthed from Qingdun, according to Wu Aihua, the museum's deputy curator.
