The first is 'happiness and beauty'.
The second is to be 'cherished in the present'. (Fading soon after flowering, the Gesang flower is a reminder to appreciate good things while you have them.)
The third is 'perseverance'. (Although its blooms fade, the Gesang flower is vital and strong, thriving in difficult environments, unafraid of hardship.)
Women are likened to the Gesang flower in Tibet, hence the name of Laoyuan's painting, with resilient, beautiful women on the grassland, all to be cherished.
