I didn't see the picture of "wintersweet wintersweet" you mentioned. Judging from the inscription, "purple gas comes from the east", the fine print should be "cold flowers bloom, old stems grow new branches", but many figures are very unorthodox.
"Purple gas came from the east" originally meant that I saw that the Zhou Dynasty was getting weaker and weaker, and my ideas could not be reused, so I ran away. Arrested by the court. Before Lao Zi crossed Hangu Pass, Guanling made Yin see purple gas coming from the east, knowing that saints must cross. Later, as expected, Lao Tzu came riding a green cow. Yin detained Laozi's 5,000-word Tao Te Ching.
Later, China people used "purple gas coming from the east" as a metaphor for good luck.
The poem "Cold ling releases fragrance, old stems give birth to new branches" is an inscription on many plum blossom pictures. Based on this, I guessed what the picture author wrote, so I said that his calligraphy skills were poor. This poem is generally inscribed on the plum blossom map, vigorous and dry, to meet the elegant character of plum blossom blooming alone in the cold winter. "Gu Gan", that is, old stems, old stems, new branches and new flowers, is a noble character that praises plum blossoms. Although it is old, it is quite lonely.
As for why the author wrote "purple gas comes from the east" and "cold ling releases fragrance, and ancient stems grow new branches" together? According to the convention of calligraphy and painting, these two sentences should not have been written together. I think "purple gas coming from the east" should be the topic that the author asks the painter.
