Bitong drink is served with lotus leaves.
Specific explanation:
"Bitong Drink" is a summer-relieving drink invented by the ancients. It began in the Wei and Jin Dynasties and flourished in the Tang and Song Dynasties. "Bitong drink" is also called Bitong cup, lotus cup, and lotus cup. It is to pick fresh lotus leaves to hold wine, then pierce the center of the leaves to connect the stems and leaves, and then drink the wine from the stems. The literati called it "The taste of wine is mixed with the fragrance of lotus, and the fragrance is colder than water."
Introduction to ancient books:
"Yin Hua Lu" mentioned that Li Zongmin, the prime minister of the Tang Dynasty, held a banquet, with lotus leaves as wine glasses. Tie the lotus leaf filled with fine wine tightly, then put it to the person's mouth, prick a hole with chopsticks and drink. If you can't finish the drink in one gulp, you have to drink it again. Use a lotus leaf as a cup and pierce the holes with chopsticks to drink. Spilling is not allowed, otherwise you will be punished. There must be many who are punished, and everyone is happy.
The drinking method of using lotus leaves as cups first appeared in the Cao Wei Dynasty. At that time, some people held banquets and drank. They used lotus leaves as cups, pierced the petiole with a hairpin, and used the stem as a tube to drink. This is called "Bi". "Drinking in a tube", according to the ancients, the feeling is "the taste of wine is mixed with the smell of lotus, and the fragrance is colder than water".
Lotus leaf morphological characteristics and growth environment:
Lotus leaf morphological characteristics:
The leaves are preferably large, neat and green in color. The stem of the lotus leaf is green and covered with small thorns, like an umbrella handle; when the stem of the lotus leaf is broken, there will be many connected threads on the stem. There are countless micron-sized waxy papilla structures attached to the surface of the lotus leaf.
When observing these papillae with an electron microscope, you can see that there are many nanometer-sized particles with a similar structure attached to the surface of each micron-sized papilla. Scientists call them micron particles of lotus leaves. Nano-double structure.
It is these tiny dual structures that make the contact area between the surface of the lotus leaf and water droplets or dust very limited, so the phenomenon of water droplets rolling on the leaf surface and taking away the dust occurs. . And the water does not stay on the surface of the lotus leaf.
Lotus leaf growth environment:
Lotus leaf is a perennial aquatic plant with rhizomes of the Nymphaeaceae family. It likes warmth and water, but the water cannot submerge the lotus leaf. The water temperature should not be lower than 5℃. The lotus roots will begin to germinate at 8-10℃, and the lotus roots will grow at 14℃. The lotus roots will accelerate their growth at 23-30℃, pull out standing leaves, pedicels, and bloom. It requires sufficient sunlight during the growth period and needs to grow in shallow water with a depth of 50-80 cm and a slow flow rate.
