The Number

280 million yuan

China has invested 280 million yuan ($45.5 million) to protect the relics of the ancient Koguryo Kingdom since it was inscribed onto the UNESCO World Heritage List 10 years ago. Dating back about 2,000 years, the cultural heritage property in Ji'an, a small town in northeast China's Jilin province, consists of the cities of Wunu Mountain, Guonei and Wandu Mountain, as well as King Haotaiwang Stele and 38 tombs for both Kogurgo kings and noblemen.
