It shows a man kneeling with his head turned, and it surprises everyone who sees it.
Making maps for protection
Wu Yunjie who was born in the 1990s found a new way—by making a special map to show the best cultural sites in China. Wu is now famous on the Internet. He marked almost 10,000 places like old temples, towers, bridges and houses. Each site with colorful marks showed how special and important they are. As a kid, Wu loved going to a temple in his hometown in Ezhou, Hubei. However, it was pulled down years ago. He was sad and decided to record all the cultural sites in China.
He started to travel across the country. He visits places in person and adds them to his map, making sure we all remember them. Now, Wu asks for help from people online to make his map better and better. And he hopes to share this amazing map with everyone who respects (尊重) history and culture soon.
