Cultural relics are found at a tomb cluster in Chengdu city, capital of Southwest China's Sichuan province. Chinese archeologists excavated nearly 200 tombs and discovered more than 540 bronze items in the cluster dating from between the Spring and Autumn Period (770-476 BC) and the Warring States Period (475-221 BC). The largest number of items was found in a tomb holding a boat-shaped coffin, which was carved out of a tree trunk and sealed with mud. [Photo/Xinhua]
