The flowers can be from some other plant. There is some vine going diagonally across the photo, from bottom right up to the left. It is with sparse single flowers all along, not as clustered as the red ones.
I thought the pink belonged to the flowers of Neillia thibetica. http://www.google.com/search?q=neil...TF-8&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&s
When I zoom in it looks exactly right for fully formed flowers... rather than buds. The flowers are tiny. see... http://www.google.com/imgres?q=neil...141&start=0&ndsp=21&ved=1t:429,r:16,s:0,i:122
