Guo Baojieying introduced: The exhibition hall is divided into three parts: "Bronze Treasures", "Jade Essence" and "Various Craftsmanship". On display are the fine cultural relics unearthed from the Noble Zhaoyu area of ​​the Guo State Cemetery since the 1990s, including two tombs of monarchs, a tomb of a monarch’s wife and a tomb of a prince. Among them, the bionic animal jades are exquisitely crafted and lifelike, and include almost all common animal species in the northern temperate zone. The iron sword with a jade handle and a copper core is even more famous at home and abroad. It advanced my country's iron smelting history by 200 years and is known as "China's first sword."
