Seaweed, a "rich" vegetable, has harsh growth conditions and can only grow in pure spring water. A little pollution of water quality or the application of chemical fertilizer in farmland will affect its growth. Therefore, people often judge whether the water quality is polluted by growing algae. The environmental protection department calls it "environmental protection dish". Where algae grow in spring water, the water quality must be of high standard. Heqingyou 18 Longtan, like Xinhua Village, is rich in seaweed, and the locals regard seaweed as a kind of food for entertaining guests.

Description: Seaweed is a rare and endangered aquatic medicinal plant endemic to China.
Seaweed is a kind of green algae aquatic plant, which is produced in Erhai Lake in Dali and Lashihai Lake in Lijiang. Jiaqing Wu in Qing Dynasty wrote in Textual Research on Plant Names: "Seaweed was born in Yunnan water, with long stems and leaves as big as the front leaves of the car, all of which were hidden in the water. Draw a long bud, with more than ten flowers in the same bud. Blooming on the water, there are three petals, and the color is white ... People pick its stems and leaves to eat. " The stems of seaweed are four or five feet long, soft and brittle, and as thick as ropes. The stem must have bracts, each bract has four or five flowers, and the four petals are white, so it is also called seaweed flower. After being salvaged from the sea, Haimou was washed with clear water and boiled with flower buds, stems and leaves and taro, which was called "seaweed taro soup". Refreshing and delicious, it is a famous dish that Bai people often eat. Seaweed grows and floats on the surface of Erhai Lake. Bai folk songs often refer to wandering life: "Dali Haizi has no root grass, and it doesn't float, fall or take root", which refers to seaweed. Seaweed is considered as the touchstone. Because it is strict with water quality, it can't grow if the water quality is slightly impure. At the same time, it is now wild and there is no record of artificial cultivation. It is only eaten by ethnic minorities in Yunnan, so it is a rare and endangered aquatic medicinal plant unique to China.
