Rainbow introduction: If you encounter heavy rain in the grassland, don’t be depressed. When the rain passes and the sky clears, you will have the opportunity to enjoy the scenery of the grassland after the rain. The mountains in the distance are as dark as black, and there is a bright rainbow in the mist; cattle and sheep are in groups, strolling leisurely on the green fields. This scene is like an eternal painting, quiet and peaceful everywhere.
