Game turns tour into lessons in history

The ancient city of Dongjing, the capital of the Northern Song Dynasty (960-1127), continues to resonate with modern-day people. Not only does it remain buried 8 to 10 meters beneath present-day Kaifeng, Henan province, but its influence is also evident in the designs of the city's contemporary tourist attractions.

I began learning about a park featuring an ancient structure from the Northern Song period through a mystery game that was popular on the internet. I decided to figure out why it was so appealing.
