HANGZHOU, Jan. 20 (Xinhua) -- Liangzhu, a cultural site in eastern China's Zhejiang Province inscribed on the UNESCO World Heritage List in 2019, has released a children's picture book about the history of pottery.

Produced by the Liangzhu Museum, the picture book, "Liangliang's Pottery World," tells the story of the protagonist Liangliang and her family. Her grandfather is a pottery master making preparations for a feast hosted by the king of Liangzhu to welcome the ruler of Fuquanshan, another site of ancient ruins that was found in Shanghai.

All earthenware items in the book can be traced in the exhibits in the museum, according to the museum.

The book is published by the Zhejiang People's Publishing House.

The Liangzhu ruins have gained world recognition as a testimony to the existence of at least 5,000 years of Chinese civilization. The pottery was popular in both royal and civilian families at that time. Archaeologists found the pottery was used as cookware, food and storage containers and tools of worship.
