What are the characteristics and symbols of lotus?

1, lotus is characterized by thick and knotty roots, which are born in underwater mud. The leaves are shield-shaped, round, dark green on the surface, covered with wax white powder, gray-green on the back, and wavy all over. Petiole cylindrical, densely barbed. Lotus symbolizes the beautiful meaning of mud but not dye, elegance, purity, honesty, auspiciousness and love.

2. The noble character of lotus "straight through, not crawling, not stained with mud, clear but not demon" has always been one of the themes of poets' singing and painting. Lotus is called "living fossil" and is one of the earliest plants in angiosperms. Before humans appeared, about 104500 years ago, most of the earth was covered by oceans, lakes and swamps. At that time, the climate was bad, disasters were frequent, there were no animals, most plants were eliminated, and only a few wild plants with strong vitality grew on this barren land. Among them, there is an aquatic plant that we call "Lotus" today, which has withstood the test of nature and stubbornly survived in amur river (now Heilongjiang), the Yellow River, the Yangtze River basin and the swamp lakes in the northern hemisphere.
