Gu Yu tea fragrance, there are poems: "poetry plum blossom month, tea fried Valley rain spring." In the tea season of the Ming Dynasty, Xu Xie said in the tea season that “it was too early to be clear and it was too late to start the summer. Before and after the rain, it was moderate.†Zhu Quan’s tea tasting, product decoction and frying in “Tea Tea†The four ways of talking about drinking tea in soups and teas suggested that tea products should be suitable for tea. Gu Yu Cha is a spring tea collected in the season of Guyu, also known as Erchun Tea. The moderate temperature in spring, abundant rainfall, plus the rest of the tea tree for half a year in winter, makes the spring shoot buds plump, green color, soft leaf, rich in a variety of vitamins and amino acids, so that spring tea tastes fresh, aroma pleasant. In addition to the tender shoots, Gu Yu Yu Cha has one bud, one young leaf or one bud and two young leaves; one bud and one young leaf of tea are soaked in water like the ancient guns that began to carry the flag. It is called the flag gun; The young leaves are like the tongue of a finch. They are called burrs; they are the best products of the year. The relevant departments such as the Chinese Tea Institute have proposed that the day of the Lunar New Year "Guyu" be used as the "Drinking Tea Day for All People," and various tea-related activities will be held.
Tea growers said that the dry tea made by Gu Yu on the day of the rain is really a Gu Yu Tea, and it must be taken in the morning. The folk also said that the real valley rain tea can make the dead resurrect, sure that many people have heard of it, but this is only a legend. I can think of how high the weight of real Gu Yu Tea is in people's minds. The tea that the tea growers picked up on that day was reserved for themselves or used to entertain guests. When they drank tea for you, they would show off to the guests quite braggingly, this is the tea that Gu Yu made that day. The implication is that only guests who come will pick it up for you to drink. Why is it necessary to keep the tea on the day of the trough of rain and drink for others but not sell it to others? What is the reason? The Tea Farmers Association solemnly stated to you that the tea collected on the day of Gu Yu’s drinking was particularly good for people’s health, and it was plagued by malaise in the whole body. He was sick and could cure the disease, and he was sick and protected against all diseases. Saying it is so godlike that you can't help but respect his tea. The "Shen Nong Materia Medica" book was said more than 2,000 years ago: "Long time comfort and gentleness ... light and stale." It seems that the tea farmers are not unfounded. Tea experts are more convincing. The reasons are as follows: First, Gu Yucha is influenced by the temperature, and it is fully developed. The leaf fat juice is full, and the soup is thick and thick, which is far better than Mingqian tea. The second is price concessions. , Value for money, suitable for people's consumption level. Under normal circumstances, after the Ching Ming Festival, the price of green tea tea fell quickly. One day at a time, it kept falling. Until one week before and after the rain, it was the psychological price of the citizens. Those tea guests often saw this opportunity. , pick some of the high quality and good quality of this time the tea produced in the possession of their own slowly to drink, in order to prepare for a year's taste. Therefore, this is the old experience of tea patrons. By this time, when you see good tea, you have to start. Because the price of tea during this time is relatively stable, you no longer expect tea prices to fall too much because You wait, when time passes, there is no good tea to buy for you.
Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.
