Tucked away in Peking University, Yanjing Lake (Glasses Lake) is a hidden gem with mirror-like waters reflecting historic architecture. The iconic arched bridge creates a picture-perfect scene, especially when autumn leaves turn fiery red. It's where scholars have sought inspiration for over a century – now you can stroll along its shores to experience that same serene academic atmosphere. Pro tip: Visit at sunset when the golden light dances on the water!
