China has many, many UNESCO sites, and by many I mean 50 sites, it is the 2nd country with most sites. The country with most sites in Italy.
It wasn't easy to get cards from all the chinese sites but thanks to Chenzhen and Danise, I've now these 2 cards of the Chengjiang Fossil Site, inscribed in 2012.
A hilly 512 ha site in Yunnan province, Chengjiang’s fossils present the most complete record of an early Cambrian marine community with exceptionally preserved biota, displaying the anatomy of hard and soft tissues in a very wide variety of organisms, invertebrate and vertebrate. They record the early establishment of a complex marine ecosystem.
The site documents at least sixteen phyla and a variety of enigmatic groups as well as about 196 species, presenting exceptional testimony to the rapid diversification of life on Earth 530 million years ago, when almost all of today’s major animal groups emerged. It opens a palaeobiological window of great significance to scholarship. - in: http://whc.unesco.org/en/list/1388
