What is less known is that there is a secret underground palace between the north and south peaks on the west side of Hangzhou West Lake, which Lin Biao built especially for himself, with the project code "704", and it is even said that this underground palace cannot even be destroyed by atomic bombs.

Here, I will unveil the mystery of the project codenamed "704" to see what is the clever design of this underground palace?

It took 14 months and cost 31 million

Decades ago, the beautiful Xizi Lake where there are so several villas were classified as a military restricted area, from afar, quiet and reveal a mysterious atmosphere, let people want to explore.

It was not until many years later that people learned that this place was Lin Biao's "704" palace, and now the "704" palace has become an attraction on the shores of Xizi Lake, all without the mystery of the year, which also gives us a chance to explore.

The reason why the palace was named "704" is that it was built in April 1970, and the location of the palace was on the west side of the West Lake, and Lin Biao chose the site of the palace between the north and south peaks for security reasons.

The location also makes the palace very secluded and difficult to be discovered.

In order to build this hidden palace, more than 7,000 civilian workers from 79 units were used at that time, taking 14 months and costing more than 31 million RMB, which resulted in this magnificent building.

The "704" palace is divided into four villas, a total of 28,452 square meters, the villa name are: One, two, three, four.

The "One Building" is the largest villa, occupying a total area of more than 12,000 square meters, this building is mainly for Lin Biao and other family members to live, the villa has a reception hall, cinema, dining room, kitchen and other places, comfortable to live.

As for "Building II", it is a swimming pool. At that time, because Lin Biao's wife Ye Qun likes to swim, so according to Ye Qun's preference, Lin Biao built a special swimming villa for Ye Qun, the pool is equipped with large air conditioning and sound-absorbing panels, in addition, it is also equipped with a thermostat device, which can ensure that the water in the pool maintains a temperature throughout the year, which is the best place to go for vacation.

The "No. 3 Building" is called the General's Building, which is used as a meeting place for guests and mainly for entertaining friends. The "No. 4 Building" was for Lin Biao's agent in Zhejiang, Chen Licheng, to live in.

Main residence "One" villa

The "One" villa was the most common place where Lin Biao and his family lived, and unlike the other three villas, it was designed exactly to Lin Biao's liking.

Lin Biao has a fear of water.

Back in 1938 during the Anti-Japanese War, Lin Biao once wore a captured military coat to the territory of Yan Xishan's troops, but who knows, the sentries of Yan Xishan's troops saw him wearing a Japanese army coat and thought he was a Japanese officer.

The sentry then fired at the "Japanese officer" without saying a word, in accordance with the instructions Yan Xishan had given.

After a "bang-" shot, Lin Biao fell in a pool of blood.

After that, several soldiers from Yan Xishan's troops cautiously went up to check, and only after seeing the face of the fallen man did they know that they had made a big mistake, where they hit the "Japanese officer", it was clearly the senior commander of the Eight Road Army!

The bullet penetrated Lin Biao's body, entering from the right armpit and exiting from the left dorsal side, injuring his vertebrae, near which there are many nervous systems.

In his later years, this problem of Lin Biao was particularly prominent.

Lin Biao is afraid of water and does not like to take a bath, so in the design of the "One" villa, the designer specially to Lin Biao to create a solarium, in order to let Lin Biao more sunshine.

The solarium, built at the back of the "One" villa, is a chic hexagonal pavilion with floor-to-ceiling windows on all five sides, each with three panes of glass.

This solarium is a glass-made room, the glass is specially made, three glass, one of which is bulletproof glass, and a glass is refractive glass, can filter out the harmful rays from the sun, so that sunbathing Lin Biao, will not be harmed by the light.

Moreover, people outside the bathroom can't see inside the bathroom.

In addition, the bathroom is equipped with a television monitoring system, so that those who enjoy sunbathing in it can monitor every corner of the "704" palace.

In order to prevent Lin Biao from hearing the sound of rain dripping down the eaves when it rains, the designers made a special drainage system so that the rain would stay in the roof tile cracks and not drip downward, and would be discharged by a dark ditch along the specially made system.

Therefore, even when it is raining, those who live here will not hear particularly loud water drops, plus the windows of the villa are specially made, as long as the windows are closed, whether it is raining or windy, there will be no noise inside the villa, just like the condition on a sunny day.

In addition, when the "704" palace was built, Lin Biao was already old and the designers took his age into consideration and used a revolving staircase instead of a straight staircase when building the staircase to the second floor of the building.

Every time you walk up a revolving staircase, you will find a transition to a resting platform at the staircase, which is the designer's ingenuity, the designer's intention is to think that Lin Biao may be old, walking inconvenience, if the staircase is designed as a revolving staircase, both good-looking, but also to build a few more resting platform.

As for the carpets in the rooms of the villa, they are also the most expensive pure wool carpets in China.

Wool is a natural fiber, carpets made of wool are not only soft and comfortable to step on, but also will not generate static electricity, not to mention insects. In addition, the designers use wool as carpet for another reason, that is, wool has natural fire retardant characteristics, fire can not ignite the wool fiber, and this also avoids the occurrence of fire.

These, are "One" villa in the special design, like this special design, can be said to be everywhere, in addition to "One" villa in these ingenious design, the other "Two" villa, "Three" villa, "Four" villa have their own unique features, here also will not be introduced one by one.

Secret underground palace

In addition to the surface of the four villas, "One Building" villa below there is an underground palace of Lin Biao, and the underground palace is also known as "704" project in the most solid place, a total area of more than 4,000 square meters.

Inside this underground palace, there are command rooms, communication and telegraph rooms, food storage rooms and backup power generation rooms, and the underground tunnels are designed to be spacious and orderly yet full of organs.

Moreover, inside this underground palace, there is also a special elevator, the elevator directly to Lin Biao's bedroom, it can be seen that Lin Biao thought that in the event of any dangerous things, he can directly from the bedroom to reach the underground palace, and shut down the operation of the elevator to ensure their own safety.

However, this is not the most elaborate design of this underground palace.

The underground palace is like a maze, there are many passages, if you do not know the route inside this in advance, it is easy to lose your way here, and these passages lead to the door, are up to 500 kg of bulletproof, antivirus, waterproof steel doors, as long as you hide behind the door, whether in the passage of water or shooting with guns, can not hurt the lives of people behind the door.

In addition, even the glass of the windows of the rooms in the underground palace are all specially made glass.

The composition of the glass consists of three layers, one for bullet-proof glass, one for UV-protected glass, and one for ordinary glass.

Looking at the passage towards the window, you will find that no matter from which angle you look, you cannot see anything inside, on the contrary, people inside look out through the glass and can see the outside in full view.

And this makes the entire underground palace a separate and secure military base.

The most ingenious thing is that the passage leading to Lin Biao's bedroom in the underground palace is an echo channel, if someone enters the place, Lin Biao can hear the echo amplified footsteps, so as to confirm the location of the comer and take precautions.

In addition, even the lamp in the bedroom where Lin Biao lived was carefully crafted by the designer.

Bedroom lamp looks a bit like a straw hat, the outside of the lamp is also wrapped with a layer of georgette as decoration, if any accident, such as an earthquake, the lamp was shaken down, its straw hat-like lamp holder and georgette, it will play a parachute protection, to ensure that even if it falls will not hit people.

What is more surprising is that the highest point of the underground palace is 26 meters above the ground, which can protect against atomic bombs and nuclear radiation, and this is one of the reasons why the underground palace is called "indestructible even by atomic bombs".

In addition, the underground palace has an independent power generation and water supply system, even if you live here for several months without going out, there will not be any problems.

This is the ingenious design of the entire underground palace, the entire underground palace is like a fortress, when a war or natural disaster, as long as the first time down from the bedroom elevator, you can ensure their own safety, but also, in the underground palace, you can still send out signals to the outside, giving orders.

According to the records of the Zhejiang Provincial Archives, the main purpose of the underground palace was to prepare for the armed coup, and the palace was also known as Lin Biao's military base in Hangzhou. The "704" Palace was also known as Lin Biao's military base in Hangzhou. When the "704" palace was built, Lin Biao built it in the name of special national defense projects. No one knew the true nature of the "704" palace except the people who designed the project, the workers who built it and the users, such as Lin Biao.

The mysterious "704" project, now a tourist attraction

In 1978, for the development of diplomacy and tourism, "704" Palace was taken over by Zhejiang Hotel, among which "No.3" villa and "No.4" villa were converted into a place for receiving foreign guests and overseas Chinese as well as for meetings.

As for the largest area of "One" villa, "Two" villa and underground palace, it was converted into a tourist attraction, a special landscape at Hangzhou West Lake, open to tourists.

The original intention of making the "704" palace a tourist attraction was to educate people by closing their eyes and contemplating from the history. When you walk into the "704" Palace, you will find that from a distance, the "704" Palace is no different from an ordinary villa complex, but when you walk inside, you will find the clever design of the "704" Palace. "The design of the palace is very clever.
