China - West Lake in autumn

This beautiful postcard shows the West Lake in Hangzhou in autumn. I really love sunny days in autumn, when it's quite warm and I can observe the colorful leafs :) But autumn in China is not only colorful, but looks also quite exotic (at least for me, because I haven't been there). The sender wrote that she loves the autumn in Hangzhou because of the aroma of the Osmanthus fragrans flowers. I don't know, what do they smell like, but I'm sure it must be a very pleasant aroma :)
