Core Points - The "Blessing the Motherland" giant flower basket has been successfully installed in Tiananmen Square, featuring a diameter of 12 meters and a total weight of 60 tons [1] - The installation process took nearly 3 hours, ensuring a tight fit between the basket's base and body, with staff monitoring all viewing angles throughout the process [3] Design and Features - The flower basket's body stands 16 meters tall and includes 18 types of flowers symbolizing positive meanings, such as roses for peace and sunflowers for freedom and happiness [5] - This year introduces dynamic animal elements, with 10 doves depicted in three different poses, marking a new highlight for the installation [5] - The inscriptions on the basket include "Blessing the Motherland, 1949-2025" on the south side and "Happy National Day, 1949-2025" on the north side, along with an increased use of new plant species like iris and corydalis [5] Technical Aspects - The design process involves confirming the colors and selecting the best techniques to achieve realistic representations of the flowers, utilizing 3D scanning technology for precise placement [7] - A total of 196 large flowers were used, with hundreds of additional filler flowers to enhance the overall appearance [7]

Core Viewpoint - The article highlights the successful reintroduction of the critically endangered species, the large-flowered stone butterfly, into its natural habitat in Yunnan, China, showcasing China's commitment to biodiversity conservation and the innovative approaches taken in species protection efforts [1][2][10]. Group 1: Species Conservation Efforts - The large-flowered stone butterfly was rediscovered by Chinese researchers in 2021 after being considered "lost" for over a century, leading to breakthrough cultivation in laboratories [2][3]. - The reintroduction of the species involved careful planting of seedlings into their native soil, demonstrating a significant step in the conservation of endangered species [1][12]. - The Southwest China Wild Biological Germplasm Resource Bank has become a critical support system for the conservation efforts, housing a vast collection of rare and endangered plant seeds [2][3]. Group 2: Germplasm Resource Bank - The Southwest China Wild Biological Germplasm Resource Bank is the only national-level facility of its kind in the country, preserving 27,000 species and 330,000 samples of wild biological germplasm, making it the largest in Asia [2][3]. - The resource bank has achieved international leading levels in the long-term preservation of various wild plant seeds, plant tissues, DNA, fungi, and microorganisms [3]. Group 3: Technological and Community Engagement - The conservation efforts are supported by advanced technologies, including genetic diversity analysis and innovative breeding techniques, which have led to the successful cultivation of hundreds of seedlings of the large-flowered stone butterfly [2][10]. - Community involvement has shifted from hunting to conservation practices, contributing to the overall success of biodiversity initiatives in the region [8].
