How mysterious is "Western Gate of Hubei Province"? It used to be a forbidden place, and it is said that head of state general Ba was placed here.

The Earth is a huge carrier, and it is place where live people. It is also limited, and habitable area must be very narrow, so problem of describing orientation and area should not be touched upon.

As we now know, there are more than 200 countries on earth, countless mountains, rivers, oceans, lakes, and many different advanced modes of transport, such as ships and planes. will exist in a large space.

And this is in a space without any geographical signs, for example, over an endless sea and in an endless blue sky, and loss of direction is very fatal for this kind of transport, so for these creatures How to accurately determine their location.

It also reflects great wisdom of people. In addition to dividing four directions of east, west, north and south, people also find several landmarks on surface of earth to accurately separate them. This is the meaning. existence of latitude and longitude.

People first consider equator as longest line of latitude, define equator as a line of zero latitude, and divide it into two hemispheres from equator to north and south, and into north and south The poles are divided into low latitudes, middle latitudes and high latitudes every 30 degrees. The higher latitude, closer poles and colder climate;

The other line is longitude line. The line of longitude starts from zero meridian. This meridian line is located where Greenwich Observatory in UK used to be. People define this as prime meridian, and use this point as a starting point to make a semicircle in two directions to divide whole earth.

However, starting point of eastern and western hemispheres is not prime meridian, but 20 degrees west and 160 degrees east. Thus, land Every country, every place in world, even a mobile ship sailing on sea, can accurately determine its own direction and position.

In today's article, we will mainly discuss issue of latitude.

As mentioned above, latitude is divided into three regions: low latitudes, mid-latitudes and high latitudes. The lower latitude, closer to equator, and higher latitude, closer to north and south poles. In northern and southern hemispheres, two parallels are more important. The latitudinal parallels are Tropic of Cancer and Arctic Circle. The first represents range of sunshine, and second represents region where polar day and polar night appear.

Because angle of solar radiation is within Tropic of Cancer, it is easy to understand relationship between regional variations and temperature. The closer to equator, hotter. Within Arctic Circle there will be phenomena of polar night. for half a year. It is easy to see that region mid-latitudes is most suitable place for human survival.

Among many points where longitude and latitude intersect, there is an area that has always been praised by people, and this is latitude line of 30 degrees north latitude, because there are too many mysterious unsolved mysteries that are not found in other places.

First of all, four ancient civilizations that we are all familiar with: ancient Chinese civilization, ancient Egyptian civilization, ancient Indian civilization, ancient Babylonian Mesopotamian civilization, are at this latitude and pass through, here not not only a developed civilization, but also a magnificent landscape.

At same time, there are frequent disasters, such as earthquakes, tsunamis, volcanic eruptions, and today's plane crashes, etc., and mysterious Bermuda Triangle. There are many aircraft in history. Both ships and ships have wrecked or been wrecked here, and there are rumors of time tunnels.

Another European country at this latitude, Italy, also has a similar existence. Although the land area is small, there are two known death valleys that threaten all birds and beasts that fly into them. Humans only. , no rest;

Also in USA at this latitude there is also a small town surrounded by forests, where strange phenomena of earth's gravitational field will be discovered, there are countless such examples.

This is why people also refer to 30 degrees north as magic line of latitude. Of course, these phenomena are closely related to Earth's own structure, crustal motion, and internal dynamics. etc. But, according to modern human science and technology, it will take time to uncover truth behind this.

The mystery of "Western Gate of Hubei Province", which I want to talk about today, is also related to thirty degrees north latitude. It is said that in dense virgin forest here and there is legendary Cave of Towers.

It is located in Enshi Prefecture, Hubei Province, including Tenglong Cave, which is one of most beautiful scenery in China. It seems that Enshi, Hubei Province is not only a scenic treasure, but also a beautiful and exquisite place.

The small county town I want to talk about today is called "Xianfeng", which has nothing to do with Emperor Xianfeng. Acquiring Xianfeng here means "Xianqingfengnian". It is known as western gate. Hubei Province, this county has a lot of primordial forests and many mountains, such as Wushan Mountains, Wuyi Mountains, and Qiyue Mountains.

And thousands of caves, large and small. This is a mysterious place that combines various geological landscapes, such as canyons, cliffs, river valleys, underground dark rivers, virgin forests and caves. In this way, it has also turned into a very attractive landscape for viewing.

Among hundreds of caves, Ba Culture Towers Cave is also very mysterious and attracts many visitors. Ba culture is mostly associated with Ba Manzi, a legendary ruler of that time. Ba Manzi is said to have made sacrifices to save his people.

Yi placed his head today in a cave in Xianfeng County, which was called Tower Cave in ancient times. The reason why people of Ba are mysterious is that this ancient and mysterious family created a civilization in Yangtze River basin, and this ancient civilization can be compared to culture of Central Plains.

However, this enigmatic family line suddenly disappeared into long river of history over 2,000 years ago. The legend adds color to unsolved mystery of Ba culture, and also makes people of later generations admire and worship her. This is another mysterious legend located at 30 degrees north latitude.
