Final answer:
More than 500 artifacts were found at Zhoukoudian, with a single tomb of Marquis Yi of Zeng revealing over 15,000 items from the 5th century BCE.
Step-by-step explanation:
More than 500 artifacts were found at Zhoukoudian, a significant archaeological site in China. In fact, the tomb of Marquis Yi of Zeng was discovered undisturbed and carefully excavated, which led to the revelation of more than 15,000 items. These items included a variety of objects such as musical instruments, large bronze vessels, and costly materials such as gold and jade, all dating from the late 5th century BCE. This is just one example among many elaborate tomb structures in China, which were part of their ancient burial practices that sometimes included sacrificing human beings to accompany lords in death.
