Here you go. The latest marriage figures for the Han showed ~ 20% drop as compared to the previous year with ~ 6 million marriages & divorce rates were up by ~ 1% standing at around ~ 3 million which is around half the annual marriage rate.

Congratulations ! Zhongguo isn't merely aping the West , at this point you're the WEST. Gone are traditional Confucian values replaced with mindless crass materialism western style.

The only good news last year was the birthrate which showed an uptick after a very long time. However this is temporary as experts suggest last year being the Year of the Dragon , a lot of couples opted to have a baby that year as it was considered to be lucky in their culture.

You know the problem with you guys ? You don't read the entire document & even when you do so your understanding of it is suspect.

If you scrolled down to the bottom of the article whose link I've attached this is what it has to say about the Chinese press.

The heavyweight champion, of course, is Chinese: a machine with the incredible power of 80,000 tons is in operation since 2013 for the giant Erzhong Group in the province of Sichuan. As tall as a 10-storey building, its use is very confidential: it seems to be used to build parts for military aircraft, like its titanic sisters. To give an idea of the power of this machine, with its 780,000 kN it could easily lift an entire cruise ship. As often happens, larger does not mean better: it is not the most technologically advanced press in the world. It was built by adapting old USSR projects from the 1980s, and is currently underused due to competition from the other giants we mentioned.

Relations between China and the Soviet Union did not improve until after 1990,

so "adapting old USSR projects from the 1980s," was impossible

As I remarked before , to begin with you don't read the entire document & when you do your understanding is suspect thanks to Baidu translate or your comprehension or both. There I've completed the sentence.

Adopting " old USSR projects from the 80s ," means adopting technology from the 80s , irrespective of when & from whom you adopted those technologies ?

You could very well have imported those old USSR plants , lock stock & barrel , in the 90s from Russia during their financial turmoil or your favourite go to country in these matters - Ukraine who were also in a similar predicament , after the USSR collapsed.

According to the Chinese literature I found on the project,

There was no Soviet technology,

This is the first time I've seen it

Look deeply , that same Chinese literature will tell you , the Chinese invented EV technology or solar & wind energy systems , etc .

I'm talking about the 80,000-ton hydraulic press

-------

In 2003, commissioned by The State Council, a group of more than 30 experts conducted research and demonstration across the country, and through the analysis of Airbus and Boeing aircraft, that the 75,000-ton die forging press was slightly inadequate, and eventually the pressure level was set at 80,000 tons. At that time, many places in the country were actively fighting for this project, and Academician Shi Changxu led the team in Deyang for many times. After 5 years of research and demonstration and overall consideration, on November 15, 2007, the large press plan was finally approved, and the National Development and Reform Commission agreed to design and manufacture the world's largest 80,000-ton press independently in conjunction with Central South University, Yanshan University, Xi 'an Heavy Machinery Research Institute and other scientific research units.

Demonstration for 5 years, construction for 5 years, and grinding a sword for 10 years, China's large press was finally completed in China. "At least a thousand people were involved in the construction." "If you add the time when the first generation of Chinese duet participated in the design, the dream has been realized for nearly 40 years." Chen Xiaoci sighed.

Yes the ground work was obviously done in China since the USSR didn't have such an 80,000 MT forging press. This is where you got your forging press ToT from .👇

The United States leadership only lasted two years: in 1957 the Ukrainian company Novokramatorsky Mashinostroitelny Zavod (NKMZ), specialized in steelworks equipment, built two 75,000-ton presses. The first one, destined for a plant in Samara, is now owned by Alcoa’s Russian branch. The second was installed in Verkhniaïa Salda and is used by VSMPO-AVISMA, the world’s leading producer of titanium and other specialty alloys. The two machines have a 16000*3500 mm work table and are 35 metres tall, 22 metres of which are under the floor.

Whatever modifications were needed to get it upto 80,000 MT , was done within China . It's also called copying tech though you may have paid for it this time as opposed to pilfering the technology which is your usual Modus Operandi.
 
On November 11,it was reported that the 125,000-ton multi-directional die forging hydraulic press and intelligent production line project undertaken by Tsinghua University Tianjin Institute of Advanced Equipment(referred to as"Tsinghua Tianjin Equipment Institute")for Xi'an Sanzhong Aviation Technology Co.,Ltd.officially commenced.Upon completion,the hydraulic press will become the world's largest nominal tonnage hydraulic press,contributing to the development of aerospace,shipbuilding,and nuclear power sectors.

Zhang Lei,the chief designer of the project and executive deputy director of the Heavy Equipment Technology Research Institute at Tsinghua Tianjin Equipment Institute,explained that the technology of heavy multi-directional die forging hydraulic presses is complex and difficult to construct.The team will employ wire pre-stressing winding technology,ultra-high pressure technology,and"orthogonal pre-tightening frame"technology to address many core issues in its design and manufacturing.

It is understood that the project is planned to have a total investment of 2.5 billion yuan.The 125,000-ton multi-directional die forging hydraulic press features multi-directional die forging and precision die forging functions,and it is equipped with advanced control modes such as constant strain rate forging,making it a key technical platform for manufacturing large precision die forgings.

It is reported that the heavy equipment team of Tsinghua Tianjin Equipment Institute has long-term experience in large aviation die forging/isothermal die forging hydraulic presses and precision die forging production processes for large forgings.Since completing the 40,000-ton aviation die forging hydraulic press,they have successively delivered major equipment in China's aviation forging field,including 60,000-ton die forging hydraulic presses,30,000-ton isothermal die forging hydraulic presses,and 1,200-ton skin stretching machines.


————By 2026,it's unclear whether it will be called American technology or Russian technology.
