与许多花卉不同，宜昌的蜡梅多生长在石灰岩地质山区，无需特别养护便自然成长，悄然开花。这种坚韧的品性，使得古代文人墨客对其倾心有加。北宋政治家、文学家欧阳修被贬夷陵时，曾写下“未腊梅先发，经霜叶不凋”的诗句，描写蜡梅不畏寒冬、生机勃发的画面，赞颂生命力的顽强与美好。
In the 1960s, France became the third country, after the US and Soviet Union, to independently place a satellite (Astérix) into orbit, and the only country to send an animal into space and – crucially, for Félicette the catstronaut – bring it back alive.
