Introduction to Huayan: Huayan is a strange flower in the Xiandu Scenic Area. It is at the east entrance of Yanmen and is hundreds of feet high. Its stamens are luxuriantly green reaching into the sky, just like a huge cockscomb flower, glowing in the morning and evening. There are thousands of changes from time to time, which is the most spectacular. On windy, frosty, rainy and snowy days, it is wrapped in light gauze and hazy, adding even more charm.
