China: Nanjing Exhibition – Resumption of Mainland Sovereignty Over Taiwan! (15.10.2025)

Beyond conventional displays, the exhibition features specialized sections on maritime culture, historical maps, and Geng Lu Bu (ancient sea route manuals). It also incorporates Augmented Reality (AR) technology to offer immersive experiences of the South China Sea’s historical and cultural heritage.

The core value of the exhibition lies not only in demonstrating China’s historical proposition and legal basis on the South China Sea issue and Taiwan question but also in helping teachers and students understand history and draw spiritual strength, said Zhu Feng, executive director of Nanjing University’s Collaborative Innovation Center of South China Sea Studies.

“Only by clearly understanding the humiliations and struggles of the past can we more profoundly grasp the importance of safeguarding national sovereignty, which serves as the foundation for facing the future and building lasting peace,” he added.

China: Chang’e-6 Sheds First-Light on Evolution History of Moon’s Dark-Side! (10.7.2025)

In 2024, Chang’e-6 made history by bringing 1,935.3 grams of lunar far-side samples back to Earth. These samples were collected from the South Pole-Aitken (SPA) Basin, the largest, deepest and oldest basin on the moon, which provided a rare opportunity to clarify the compositional differences between the near and far sides and to unravel the long-standing mystery of their asymmetry.

“The SPA Basin is one of the moon’s three major tectonic units, measuring approximately 2,500 kilometers in diameter. The energy from the impact that formed this crater is estimated to be 1 trillion times greater than that of an atomic bomb explosion. Yet, the exact influence of such a massive collision on the moon’s evolution has remained an unsolved mystery,” Wu Fuyuan, an academician of CAS and a leading researcher with the IGG, said at a CAS press conference on Wednesday.

The four papers published in Nature systematically reveal, for the first time, the effects of this colossal impact, which is the core highlight of these findings, said Wu.

Imperial Japan Germ War-Fare Unit 1644

China: Memorial Hall of Victims Obtains “Roster” of Japanese Germ-Warfare Unit 1644! (14.6.2025)

“The roster reaffirms the ironclad evidence of Japanese militarism’s biological warfare crimes,” Zhou added. “We will deepen archival research and integrate these materials into exhibitions and historical education to speak with facts, uphold a correct perspective on WWII history, and defend justice and peace.”

Lyu Jing, associate professor of history at Nanjing University, noted that the roster enables “systematic research on the unit and uncovering the structure of Japan’s germ-warfare system,” adding that preserved Unit 1644 sites could “advance heritage protection and promote public memory reconstruction and peace education.”

The acquisition followed Japan’s National Archives’ first public display of the rosters of Unit 1644, Unit 8604, and Unit 8609 on May 14. During the invasion of China, the Japanese military established several biological warfare units to launch attacks, among which was the notorious Unit 731 in northeast China.

Technological Breakthrough!

China: Socialist Tech-Breakthrough in “Terahertz Wave” Control! (24.1.2025)

The newly developed terahertz wave polarization modulator outperforms other existing models, offering enhanced multifunctionality, a broader operating bandwidth, and high-precision control.

Terahertz waves, which occupy the spectral region between millimetre waves and infrared light, are characterized by broad bandwidth and strong penetration capabilities, making them highly promising for applications in next-generation wireless communications, material testing, and bio-medicine.

The research was jointly completed by the Aerospace Information Research Institute and Nanjing University. Its results have been published in the international academic journal Optica.
