An Attractive Cloud Wave

I always love to look up to the beautiful blue sky in sunny day. Today I find this wave of white cloud that looks like going to cover up the whole sky. The moment I capture these photos, it makes me feel like watching the special effect of Hollywood science fiction movie. Well, I know I am thinking too much because it ends up no UFO flying out from the thick cloud and attack us, or join us in the CNY reunion dinner :)
