Of course, the question of whether the Capital Academy of Sciences would have hidden "Zheng Kingdom" was quickly clarified. However, within only half a month, Zheng Nan accepted three consecutive inquiries from the National People's Congress Finance and Economic Committee.

Facts have repeatedly proved that the National People's Congress of the Taiping Heavenly Kingdom, which shoulders the interests of all the people of the Celestial Empire, not only has extremely high work efficiency and a strong sense of responsibility, but also emphasizes science quite.

With a history of more than 500 years, Tianjin Old Town, one of the models of China's "Acropolis", needs to undergo large-scale transformation in the southwest urban area among the four concentrated residential areas of the old town distributed in the northeast, southeast, northwest and southwest corners (the northeast and southeast corners of Tianjin City were mostly merchants and wealthy households in the northeast and southeast corners, generally not only had magnificent buildings, but also had deep courtyards and large houses. The southwest urban area, due to its low terrain, has become a gathering place for poor people. Therefore, in the past, Tianjin had always been circulating that "the north gate is rich, the east gate is noble, the south gate is poor, and the west gate is poor") will be preserved intact.

Since Shijiazhuang Village, located at the intersection of Jinghan Railway and Shitai Railway, was recently a new city that was key to development by the Celestial Government. In order to more conducive to the future development of Shijiazhuang City and thereby drive and promote the surrounding economy, all the Hebei Provincial Government, the Governor's Office and the Communist Alliance, which were originally located in Tianjin, should be moved to Shijiazhuang.

In order to better protect the old city of Tianjin, the Tianjin Municipal Government, which already has resettlement in the city, will also move from the old city to the other side of the Haihe River. The Red Navy headquarters that is planning to move from Beijing to Tianjin cannot enter the old city of Tianjin, but instead stationed in Tanggu.

All industrial and mining enterprises and residential areas required to resettle new population must be built in various designated functional areas outside the old city of Tianjin...

Although Tianjin's underground drainage system project is indeed a bit huge at the moment, this expenditure is based on safeguarding the long-term interests of the people of Tianjin. It is a necessary measure for predecessors to plant trees and later generations to enjoy the shade. It is worth it.

After many debates, Zheng Nan's reply on behalf of the State Council was approved by most members of the Standing Committee of the People's Congress, and the plan of the Capital Academy of Sciences was implemented.

In the following two years, Tianjin became the fourth municipality of the Taiping Heavenly Kingdom after Nanjing, Shanghai and Beijing.

In fact, there are many disputes like Tianjin's underground drainage system project among the top leaders of the Celestial Empire. For example, in the development of the Red Navy, there were also differences between Lin Haifeng, Zheng Nan, Yang Xiuqing and Shi Dakai on certain specific aspects.

In 1859, after the French ironclad ship "Glory" with a displacement of 5,630 tons set sail for the first time, the British ironclad ship "Warrior" with a displacement of more than 9,000 tons was also built at Thames Ironworks and the shipyard.

With the birth of these two ships covered with iron armor and being regarded by the world as the first two steam armored ships in the world, the world's navy has begun to enter a new era of giant cannon ships.

According to the information obtained by the Ministry of Internal Affairs, from 1861 to 1863, the British Royal Navy not only owned the sister ship of the "Warrior" "Black Prince", but also had been equipped with more than ten ironclad ships including "Defense", "Resistance", "Hector", "Heroes", "Achilles", "Calidonia", "Warring", "Warfu", "Ocean", "Royal Oak", and "Royal Alfred".

The above ironclad ships have one common feature, that is, their displacement must be at least 6,000 tons, and they are all authentic giant ships.

Not only that, according to the reliable information of the Ministry of Internal Affairs, construction began in 1861. It is expected that the latest Minotao-class ironclad ships to be officially equipped to the Royal Navy fleet will have a displacement of more than 10,000 tons until the end of 1863.

On the other hand, Yang Xiuqing and Shi Dakai had to frown in the Red Navy of the Celestial Empire.

Of course, for Yang Xiuqing and Shi Dakai, they would never know nothing about the real development of the Red Navy like outsiders. It is precisely because of this that they would even more incomprehensible about the research and development of naval equipment under the leadership of two smart men, Lin Haifeng and Zheng Nan.

Under the leadership of Lin Haifeng and Zheng Nan, and with the unremitting efforts of the scientific and technological personnel and construction workers of the Celestial Dynasty, the Red Navy also had its own iron ship. But what made Yang Xiuqing and Shi Dakai regret that compared to the British, whether it was the Beijing-class destroyer that had been released or the Kunlun-class cruiser that was secretly constructed in the Dalian Shipyard, they had never escaped the image of "tadpoles".

Although Yang Xiuqing and Shi Dakai did not know as much about more modern knowledge as Lin Haifeng and Zheng Nan, they were very clear that no matter how strong or good at beating a child, if they met a giant standing in front of him, they would only be beaten.

Why don’t we build a few large ships?

With this question in mind, Yang Xiuqing and Shi Dakai waited until 1864.

The two major shipyards affiliated to Shanghai Oriental Industrial Corporation, Hudong and Jiangnan, were secretly built on the Yuefei-class ironclad ships "Yuefei" and "Wen Tianxiang".

These are two truly heavy ships with a standard displacement of 11,000 tons.

However, this giant ship that made Yang Xiuqing and Shi Dakai really excited for a while was just two of them in the overall arrangement of Lin Haifeng and Zheng Nan.

So, in 1865, with the start of construction of the "Dongfanghong-1" cargo ship in Tianjin shipyard, this disagreement reached its peak.

The "Oriental Red One" transport iron ship is the latest ship design results that have finally matured after repeated experiments and demonstrations in many aspects.

In the construction of the hull of "Dongfanghong-1", researchers of the Tian Dynasty adopted a longitudinal skeleton structure and a grille double-layer bottom structure. Since this double-layer bottom extends to the two sides to above the load-load waterline, a double-layer hull was formed. In order to increase the strength of the hull, the designers also adopted the same structure on the upper deck.

The total length of this "Dongfanghong-1" iron ship is nearly 210 meters. The interior of the ship is divided into more than 20 cabins by vertical and horizontal bulkheads. It can carry 5,000 people and load more than 6,000 tons. The displacement reaches 30,000 tons, which is even 3,000 tons larger than the British "Big East", which is the largest cargo ship in the world.

In terms of power, the "Oriental Red One" is beyond the reach of the British "Big Oriental".
