1 Of course, the first reason is that the air is too dry, the indoor humidity is too small, the air is too dry, and the lack of water in the body leads to dry nose. If it is not relieved in time, it will soon lead to rhinitis and even a cold. So when you feel your nose is dry, you should drink more water. You can also put a humidifier in the room to make the air less dry.

Another reason may be that your body lacks vitamins, which can also cause dry nose. If you eat too greasy, salty and spicy food every day, it is more likely to cause nasal congestion. So eat more light food, eat more fruits and vegetables, and supplement vitamins. Put your nose on it? Hey? Ning? Improve dryness and itching

In the 1920s, a test runway several kilometers long was built in the southwest of Berlin, which became the embryonic form of expressway. Now this runway has become a part of expressway A 1 15.

On August 6th, 1932, after three years of construction, the 20km expressway from Cologne to Bonn was completed and opened to traffic. At the inauguration ceremony, Adenauer, then the mayor of Cologne and the first German chancellor after the war, declared that this expressway would show its future. This section of expressway has been used to this day and is a part of A555 expressway.

In the context of the global economic crisis, a few months later, Hitler was elected to power in chaos. He was keenly aware of the great value of expressway. He recruited unemployed people on a large scale to build expressway, which quickly reduced the unemployment rate, reversed the economic situation in a short time and won the trust of voters. At the same time, in this way, Germany also quietly built a wartime rapid transportation network. At present, 1. 1 1,000 km of expressway is called "Hitler expressway". In 2 12 BC, after the unification of the six countries, Qin Shihuang built the "equator" leading to the original capital of the six countries with Xianyang as the center. In order to defend Xiongnu, he also ordered general Meng Tian to build a highway from Yunyang County, Chunhua County, Shaanxi Province, not far from Xianyang, to Jiuyuan County, west of Baotou, which took two years to complete. It starts from Jiuyuan County (now Jiuyuan District, Baotou City, Inner Mongolia) in the north and reaches Xianyang and Qin Dou (now North Ganquan Palace, Chunhua County, Shaanxi Province) in the south, with a total length of more than 700 kilometers, which basically keeps the north-south trend, so it is called "straight road". The existing pavement is generally 23 to 26 meters wide, with the widest point reaching 47 meters, and the slope is gentle, which is equivalent to today's secondary highway (provincial highway) standard. This became the first expressway in the world.
