The situation is easily very firm, also be closed in the medium plain of separate the power to control.Week consequently interest, Qin consequently interest, the man is consequently cheerful, Sui consequently interest, Tang consequently cheerful, this gold Cape hence become Chinese history before expect several bases of big important dynasties.
Close Long to also have a disadvantageous place certainly.Four fill of the reverse side of power is that the plain is smaller, the geography Xia urges.Thus economy development the potential is limited, the population extends ability limited the creation of outstanding person is also limited at the same time.Use plain in pass as the political center of whole country, usually face the pressure of local area production shortage, is a very typical problem.
Actually by this ages, it is a ground of to close Long the man is from the east beginning drive marginalization, its economic power cultural real strenght's falling behind situation development is one of important reasons.
However always of come to say, close a Long region still in this ages elephant posterity not so develop excessively, the development degree of other regions is still limited.By so doing, pass Long and other regions compare, its economic power and the amount of populations are unlikely to fall bestill hind too many.And the advantage of geography, militarily want to have excellent, is still opposite and easy.
Consequently in the South and North Dynasty last years of the period, the pass Long newly arisen military nobility group became this stage the victor finally.Their victories give the pass Long the region to bring a lot of political advantages again, all the city, official hierarchy and powerful family, troops and supplies comes together here and occupy pass medium can get all these, as well the folio bureau is very beneficial.
Whereas, "four fill" formed by the mountain and stream river of Hebei, but not so tight.
The center of Hebei is the big slice of impact plain of yellow river downstream is also a plain north China."Four fill" situation of north China big plain is as follows:The west is the east of Shanxi to go mountain too much;File in the mound region of the south south of Shandong half;The east is an ocean;The northern side is a Yan mountain.We see here, in addition to east the ocean of the noodles in this ages calculate up more credibility outside, other three sideses are all not so dependable:
The Yan mountain of the northern side mountain range weaker, it is easy to offend to break the strong horde on the northern steppe.
West noodles' going mountain to pour too much is really the Chong mountain Jun Ling, can that is to belong to Shanxi, controling the influence of the river area of central part Fen in Shanxi has to rob descend go mountain too much still more convenience to order son.
South the mound region in the noodles not too Gao Da Dun,google, and then belong to Shandong, even blocks live half, another half still keep being a plain, always connect to Henan Central plains the region went.
So Hebei it"four fill" is in fact very spacious, the region leads long the scope pulling to lead widely and take Hebei as the setting up separatist regime of base political power and guard the on all sides opposite pain.Rise to also have at the important dynasty of Hebei, for example east man be such.Moreover, the beyond the frontier horde takes Hebei as enterprising China of base and gangplank, but is the most familiar mode.Northern side mountain range in Hebei is superficial to easily break, the beyond the frontier horde stands firm a heel to compare in Hebei Long to commence convenience from the pass.And the beginning of beyond the frontier horde rise the groundwork is on the steppe and pour to not too care western noodles Shanxi to go the natural cover of mountain too much, because of can direct from make big twists about attack Shanxi and close regions like Long,etc on the steppe.
At the same time, the spacious geography in Hebei, brought the advantage of economic population naturally.Yellow river downstream north China big plain, have the stronger agriculture the production potential, at economic foundation on also have more populations and more prosperous culture.
In this ages in,cnn, take Hebei as the political power of base also not is don't acquire an end victorious of hope of.Front generation the precedents with the east the man don't say, slightly earlier son the fresh vulgar clan from beyond the frontier builds up of North Wei, is also occupy Hebei first then unified the whole yellow river river valley.Sui end greatly disorderly Hebei flowed out now one large numbers of"robber"s and finally put together to win but the Dou summer influence of , bring Li Tang's unified war a but again, again but three"is big bother".Tang is ex- to expect to input the huge supplies of city teacher to mainly as well come from Hebei after being unified, behind expect Hebei to appear a long-term Fan town to set up separatist regime central political power of situation hard control-above various, can explain Hebei of pre-eminent.
Come to see "silver side" of yellow river river valley again, since Shanxi and Shandong.Because the yellow river river valley is a thing two capes contend for winning, so Qian at west Cape pass Long and Shanxi of the of eastern Cape Hebei, its strategic meaning nature stronger than Shandong.
The mountain and stream situation of Shanxi is total of come to say, very the elephant is a big chock that the Shu puts in the of closing the Long, Hebei.There is south here north lengthways of three Tashan veins, from the west eastwards respectively BE:Lyu Liang's mountain range, too house mountain range and go mountain range too much.The of three veins in Tashan then clips two bottoms sink of plain valley, the mankind always gather to reside more on the flat ground, so these two valley bottoms in the line plain become the key figure place that controls Shanxi region.
Lyu Liang mountain range with too the of house mountain range is a Fen river area, from north to south number come, Fen river of flowed to drip to slice in Tashan three compare bigger plain region:Is northernmost greatly with there are two pieces of smaller plains in the region and was called Ma Yi or Shuo state at that time;After once wore pass in the wild goose door and a canyon that doesn't grow toward south, central part too original there is a piece of and bigger plain in the region, at that time be called too at first, Jin sun or combine state;After go toward south again once wore a very long Qiao rat valley, the south Jin south there is a piece of and bigger plain in the region and was called river at that time east.
With Ma Yi, too original, river east three grounds of string together Fen river the area is a Shanxi's most of plains district are naturally a Shanxi's most important economic centers, population center and politics, military center.Is basic the come up to say, canned control Fen river area easily control the whole Shanxi, that is right.Among them again the ether is original, river the eastern two sides are the most important, because these two pieces of real strenght with biggest plain are the strongest.
At the same time Shanxi since is "chock" of of thing two capes, join the army matter angle to see, too original and river east also at the right moment respectively become east to enter with west enter of breakthrough.The too original eastern side is a famous well Xing pass, in the past pass Long take the offensive Hebei, usually use this as break to order, with pass Long for the northern week of base, destroy to take Hebei as the north of base together, walk of is this road.The western side of the river east then separates yellow river with plain in pass to mutually hope, is also a very familiar choice from the river the east pass through yellow river aggression the pass, north week at the beginning is also guarded river east, hold to protect to close medium front door thus.
Too house mountain range and go mountain range too much of have a smaller basin, from too original region the south wear toward the east entrance to valley too, again fold toward the south after a long valley, the south long cure there is a piece of basin in the region and was called the party or the Lu state at that time.The basin that clips in Shan-li has no big river to cross so the basin Xia urges, the real strenght is also a little bit weak.
Join the army matter angle to see, the importance of last party to Hebei is stronger than pass Long, because from here can with eastern Fu the pass get into Hebei region, can also southern courtyard pass bottom Henan again eastern enter Hebei.
The China of "grass belly", for open bureau to say to really isn't a good place, however absolutely be unequal to say that it isn't an important place.Is Central plains the ground of Fu Cou everywhere, on all sides can reach although can not help to be subjected to an enemy everywhere,turn over to say to everywhere attack again very convenient.The meaning of this fact lies in:The Central plains unwell cooperation opens a bureau, but very suitable the time in"the second step" consider taking down.Is also say, after opening a bureau to stand firm dime first, the second step takes down China and take dime as rear according to, with Central plains for front shot base.Backing can guard but the base remain a firmness, entering can offend from Central plains set out to sweep other direction of separating the power and having very great convenience.
Central plains the mountain and stream situation of region seal shut, four cent world.
Is so-called seal shut, lie in Central plains a region not one horse the big plain of the even Chuan a cake of, yellow river, Huaihe, and mountain range...etc. will Central plains partition in the region surround into four parts, since:The Hanoi region of the Luo sun plain, the north,the southern sun basin of the south and the river valley of Bian Huai of the east of west, central part.These four place difference to in response to world eight square, Central plains Fu Cou everywhere, from be thus.
The Luo sun plain is Central plains placed in of western, central part:West noodles the famous Yao mountain and not that famous bear ear mountain partition and the transportation closes in;South noodles Fu two mountains of cow, outside square partition south sun;The east famous Song mountain blocks before the river valley of Bian Huai;The northern side yellow river separated Hanoi region.Be Central plains in, the importance in the Luo sun plain from don't need speech.The week of the east and east the man all take Luo sun as all city, Yang Sui also in the pass of Chang-an outside,Facebook, list as the easts to the Luo sun all to control the whole pass east region.The Luo sun is a pass east of romantic collect of ground
