Gesanghua is a Tibetan name, which translates into happiness flower. In my hometown of Inner Mongolia, this kind of flower can be seen everywhere in summer. People in eastern Inner Mongolia call it flying all over the sky, which is the most common flower in the flower beds of institutions and schools. The branches are tall and thin, the flowers are bold and beautiful, the flowers are light and smart, flying and blooming in the sky, and the flowers are white and pink. This may be the origin of "flying all over the sky".
I am a Gesanghua from little town on the prairie, the Great Wall, taking root and sprouting in Beijing.
