What song is a cloud floating in the blue sky?

Wang Aihua sang it. "A Cloud Drifting in the Blue Sky" is the title of a song sung by Wang Aihua. Lyrics excerpt: A cloud floats in the blue sky, just like I am drifting on the grassland, with boundless green grass and boundless autumn colors. How lonely will a cloud be? A cloud floats in the blue sky, drifting away my deep feelings. I am looking for flowers in the grassland, and I only have sad love songs in my heart. A cloud is too vast to choose from east, west, north and south.
