Since the Qin and Han dynasties, Haitong, China, has two most active locations: Langya and Panyu. Since the country of Yue withdrew from Langya and continued to move south, the Yue people finally found the rejuvenation point of Panyu.
When the South Vietnamese people took Panyu as the starting point to go down to the South Sea and the Western Ocean, Langya led by Fang Shi and lured the dynasty to the sea with You Immortal as a call, first Xu Fuzhi to the Qin Emperor, from Langya to the sea, set off the first wave of You Xian. Han Wu came one after another, more magnificent than the Qin Emperor, respectively from the east and south to the sea, the east to travel immortals, the south to recruit an.
Zhao'an is politics, based on the geopolitical needs of the country, You Xian is also politics, reflecting the individual political needs of the monarchy, and immortality is the biggest politics for the emperor. If the emperor wants not to die, he must become an immortal, and to be an immortal, he must start with Youxian.
Chinese immortals are different from Western gods, Western thought, with God as the logical starting point, God created the world, man is created by God, therefore, man to man, God to God, whether it is one god or pan-god, must be divided into two gods and people.
Chinese thought is different, the world is not a divine creation, but a natural formation, whether that nature is materialized qi or ideological Tao, it can be transformed, and people can not die and transform into immortals through nourishing qi and attaining the Tao. The emperor is in the world, extremely authoritarian, there is nothing to fear, but afraid of death, escape to life, only You Immortal, so, a professional priest appeared to guide You Immortal.
Fangshi, in the Rites of Zhou, is in charge of prison litigation, like a judge, far from the gods. Qin and Han Fangshi, mainly from Yan and Qi during the Warring States period, close to the coastal area, in addition to "chatting the sky", there is also "health preservation", which is also a source of thought for the art of Fangshi. "Health" has three aspects, one is physiological, the second is psychological, and the third is reason. From the body to the mind, from the heart to the way, from these three aspects to practice, the immortal root seedlings are established.
In fact, eternal life is an ultimate goal, "looking ahead, ignoring behind", no one can dominate. People have a death, this is common sense, and beyond life and death, is human greed, of course, we can also put it another way, greed is the will of God inherent in human nature, the pursuit of God has become the driving force of civilization.
Of course, people must have lofty goals, but reality is more important, and in the pursuit of eternal life, some realistic achievements will be left, such as the Qin Emperor Han Wu. "Hanshu Art Wenzhi" divides Fangshu into two categories: "Fangji" and "Shushu", "Fangji" includes medical classics, jingfang, fangzhong, and immortals, and "arithmetic numbers" include astronomy, calendars, five elements, turtles, miscellaneous occupations, and form methods.
The world of Fangshi is a place that connects the world and immortals, and Fangshi is the key to transforming people into immortals. The reason why the emperor is an emperor is not by his own strength, but because he can be a soldier in the world, use soldiers to fight the world, use officials to rule the world, and if he wants to rule the world, he must use fangshi, because they hold the immortal side in their hands, and the culture of the two Han fangshi is very blazing. For example, during the Warring States period, Fang Shi Zou Yan, a native of the State of Qi, proposed the "Great Nine Prefectures", which encountered an echo wall in the Han Dynasty, and the Han people adopted its words, and compared with the legends of the "Classic of Mountains and Seas", it was found that in the "Great Desolate Southern Classic", there was "the country of immortality", in the "Hainai Jing", there was "the mountain of immortality", and in the "Overseas Southern Classic", "the immortal people". The "Classic of Mountains and Seas" has a very early origin, it is a classical book, or it is said to be written by Xia Yu, but its completion was compiled by the father and son of Liu Xiang and Liu Xin of the Western Han Dynasty.
The Han Dynasty re-studied the scriptures, but it was also good at weft learning. Jingxue, standing in national temples, making more political signboards, using Confucianism to "govern the country with righteousness"; Weixue, on the other hand, lives deep in the imperial secret room and interprets the code of the Mandate of Heaven, so he uses the way of the Fangshi to darken the immortals.
From Kunlun to Penglai, from Heyuan to Yinghai, the Han people have risen the craze of Fangshi Youxian, is it an imaginative space like "Mu Tianzi and the Western Queen Mother Meet", or is it a historical existence that can be restored through research like Zhang Qiantong's discovery of Kunlun Mountain in the Western Regions? In Fangshi, the two have been combined, and mythological existence and historical existence are unified, and the way to unify is to travel immortals. Zhang Qiantong to the Western Regions, of course, is not You Immortal, but at the same time it also satisfies the feeling of Emperor Han Wudi's You Immortal, Emperor Han Wudi used troops in the Western Regions, and was fascinated by Kunlun and Tianma, just like You Xian.
In addition to Tongxi Regions and Dingkunlun, Emperor Wudi of Han also opened up a great era of navigation for dynastic China in the way of traveling immortals. In Chinese history, he lifted the two major border troubles that had existed since the pre-Qin Dynasty, the Northern Xiongnu and the Southern Baiyue, and he drove the Xiongnu to the west of the roof of the world and the Baiyue people down the South China Sea.
What even Qin Shi Huang failed to do, he Han Wudi actually did it, what is the annexation of the Six Kingdoms? That is to take care of China's internal affairs, to be able to open up the territory and sweep away the northern Di Nanyi, that is the real emperor of the ages!
Land defense, coastal defense, there have been since the Qin and Han dynasties. land defense, to take the river loop, strangle the throat of the Xiongnu; Haiphong, should be stationed in Langya, seize the Baiyue dragon head. The land defense has a frontier and can build the Great Wall. The sea is borderless, dazed and defenseless, only wandering immortals.
Therefore, Emperor Wu patrolled the sea and played the card of Youxian, which could not only adapt to the psychological needs of self-deification, but also bring business to coastal residents and overseas displaced people. During his 54-year reign, he went to sea at least 7 times, and each time, he had to throw gold and silver on the sea to create a wealth carnival, don't think that the emperor was just playing the addictive fairy game, in the game, there was a promotion of national defense, and there was a development of coastal defense industry related to it, such as going to sea for shipbuilding, alchemy for iron casting.
In the Han Dynasty, shipbuilding was built many "building ships" and used them as the name of the navy. The sailors were known as the sergeants of the building, and the colonel was also called "the building ship". The height of the ship is more than ten zhang, the hull is divided into three layers, the first layer is "Lu", "like the house", the second layer is called "Feilu", and the third layer is called "Sparrow Room", which is equivalent to the outpost of the lookout, "like the warning of birds". As a warship, the three levels are defended by female walls, covered with leather to protect against the arrows and fire, and can also be used as shooting cover.
According to the "Shiji Pingzhun Book", the Han Dynasty's large-scale building ships were caused by "Yue's desire to fight with Han ships", so Emperor Wu ordered that in the royal Shanglin Garden of "eight waters around Chang'an", Kunming ponds were chiseled, building ships, and water trainers were prepared to fight a water battle with Zhuyue.
Therefore, in the Kunming Pond, the Jing flag was displayed, and from time to time there were building ships, sometimes as many as a hundred.
The water war of the Han Dynasty, just like its galloping desert, driving thousands of miles, is also across the sea, invincible. Originally, the armament of the Han family, the horse was inferior to the Xiongnu, and the ship was not as good as Baiyue, and by the time of Emperor Wu, the Han horse was not only equipped with a saddle, stirrup, and horseshoes, but also the Han navy division crossed the river with a building boat and went to sea, condescendingly, and achieved an overall overwhelming advantage.
The Han Navy Division is about 200,000 people, and it is said that more than 2,000 ships can be dispatched in a single battle. But the building ship is a warship, can not be used for the emperor to patrol the sea and travel immortals, not to mention that Shanglin Garden is originally a royal garden, chiseled a pool, a show of water division, is advertising the world, the Han family wants to use troops against Zhuyue, can not really use it as a water division base, in fact, it is more like a You Immortal base.
The most dazzling thing in Shanglinyuan is the "Yuzhang big ship", which is larger than the building ship, and according to the "Taiping Yuyan", it can build a palace and house tens of thousands of people. This is even larger than the Ptolemaic giant ship in the Hellenistic period, which is a catamaran warship with forty oars, Plutarch mentioned it in the "Greco-Roman Famous Biography", saying that it is 128 meters long, with 4000 oarsmen, 400 sailors, 2850 soldiers, and a total crew of 7250 people. The so-called "Yuzhang approximately", that is, there is no specific number out, and the credit is insufficient.
However, the scene of the drill in the Kunming pool is probably the first in China and abroad, and suddenly on the ship, the soldiers shake and beat the drums to urge the army; Suddenly, on the "Yuzhang Da Gong", the palace maid sang, and the clear sound went around the palace view. In addition to military exercises, he also performed You Xian, and even used You Xian to declare the sea power of the Great Han.
In the Han Dynasty, "a ship carrying a thousand people" was mostly a building ship. Yuzhang, which was the base of the navy division at that time, was also a shipbuilding base, and most of the ships built were building ships, which was related to its geographical location and strategic position in Jiangnan.
Emperor Wudi of Han patrolled the sea, using You Xian as a gimmick, and when he was facing Qi Di in the east, tens of thousands of people came to talk about the stories on the sea, which was fashionable. Emperor Wu used a large fleet of thousands of people to accompany him to Penglai, while he himself drove the patrol floating palace, Yuzhang Dajiang, along the Bohai Bay.
After two cruises, he made a move, from Shandong and Liaoxi by sea and land, the commander of the navy, or the general Yang Pu of the Lou ship, coincided with the civil strife in Korea, took it in one fell swoop, did not set up a vassal state, changed the county to a county, and divided the entire Korean Peninsula into four counties to administer, namely Lelang County, Hyunjin County, Jinban County, and Lintun Gun, until Goguryeo and Baekje established a state on the peninsula in the fourth century AD.
In this way, Emperor Wudi of Han unified the sea power of the more than 18,000 kilometers of mainland coastline from the Bohai Bay to the Beibu Gulf, and also administered the Indochina Peninsula and the Korean Peninsula, the two peninsulas in the north and south, with a centralized long arm.
