Why is the water in West Lake so "rich"?

🛶"I cannot leave Hangzhou, for half of my heart is here in this lake."🎋 - 🌟Must-see attractions 🌉Broken Bridge: This ancient bridge, steeped in a thousand-year-old romantic legend, remains poetic even without the presence of Xu Xian and Bai Suzhen. On the lake, boats glide slowly, leaving behind beautiful arcs. 🚣Boat ride: The boat drifts leisurely on the lake, as if you are in a moving painting. You can choose a hand-rowed boat for a more leisurely experience, or a large boat for a more comprehensive view of the lake. 🗼Leifeng Pagoda in the Sunset: At sunset, the afterglow of the sun bathes Leifeng Pagoda, turning the entire West Lake orange-red. At this moment, West Lake resembles a fairy draped in a golden veil, breathtakingly beautiful. - 🌥️In the early morning, West Lake is shrouded in mist, perfect for taking hazy photos that capture the essence of a landscape painting. ✨"If I compare West Lake to Xizi, it is always beautiful, whether in light or heavy makeup." No matter when or from which angle you look, West Lake has its unique charm. -
