Last year, people expressed great surprise at a map. It clearly shows the country’s historic sites and cultural relics (历史古迹和文物). The map was made by Wu Yunjie, who was born in the 1990s, CCTV News reported.

Wu is crazy about cultural relics and has a deep interest in history. When he was in college, he would often make use of his free time to travel around the country, exploring and recording the details of historic sites. In 2020, he started collecting information on cultural relics and making the map.

Wu spent a lot of time on research and carrying out on-site visits. Though faced with many difficulties, Wu has joy in “this job”.

So far, Wu has traveled to nearly 30 provinces and cities across the country, visited over 2,000 cultural relic sites and more than 200 museums, and taken over 300,000 photos.

Now, the map he made has nearly 10,000 historical landmarks with different colors: Red signs (标记) show the cultural relic sites under state protection (国家保护) or the national-level museums, while green signs stand for the provincially protected historical sites.

The map is popular online, and a person posted, “I actually found the old tower around my house on the map!” However, in Wu’s eyes, the map is not perfect. It cannot be shared as an online map yet.

But Wu has been working on improving it. “If possible, I also want to record the cultural relics that have been lost overseas. They may not be able to return to their homeland right now, but the stories that they carry are what we need to know.”
