The source provides a detailed overview of the increasing adoption and strategic importance of blockchain technology in China, positioning it as a key mechanism for addressing the nation's "social credit formation" weaknesses. Authored by IT journalist Makino Takefumi, the text explains that blockchain's characteristic of being highly resistant to tampering makes it crucial for ensuring the reliability of recorded information, particularly in areas like food traceability. Beyond digital currency such as the digital yuan, the article highlights numerous applications across eight major sectors, including finance, healthcare, judiciary, and government administration. The text also includes a technical explanation of how hashing and decentralized ledgers function to secure the blockchain's integrity, noting that the central government's designation of the technology as a national strategy has spurred rapid development across cities, banks, and universities. Overall, the source demonstrates that blockchain is actively being integrated into various aspects of Chinese society and commerce to enhance transparency and trust.

The provided text is an excerpt from a newsletter or article titled "まぐまぐ春節" by IT journalist Takemi Makino, focusing on the changes to the Chinese New Year, or Spring Festival (Chūnjie), due to the COVID-19 pandemic and the pervasive influence of technology. The article explains that travel restrictions led to a new phenomenon of people staying in cities to celebrate, known as "Yuánnián rén" (原地過年的人), and the rise of digital traditions like video greetings ("Yún bài nián") and mobile payment gifts ("Yún hóngbāo"). Furthermore, the text details how tech companies view the Spring Festival as a crucial period for expanding their services into less penetrated areas, specifically the "sunken market" of smaller cities and rural areas and the "silver-haired market" of the elderly, leveraging returning urban youth to teach their relatives about new technologies and digital services.

The source, an issue of the newsletter "Keywords for Deeply Understanding Chinese IT," focuses on the recent surge in electric vehicle (EV) sales in China, which many media outlets describe as happening "suddenly." This growth is attributed partly to the COVID-19 pandemic, which shifted consumer preference toward private transportation, minimizing contact, and also to the rise of "smart" EV features that appeal to younger consumers (Z Generation), who view cars as a "technology device" extension of their smartphones. While affordable micro-EVs like the Wuling Hongguang MINI EV are hitting record sales, higher-end models from companies like Tesla, BYD, and Nio are also performing well, challenging the previous view that China's EV shift was struggling. Despite this positive trend, the article notes that EVs still represent only a small portion of overall car sales and that hitting the government’s 2025 sales target of 20% will depend on successfully penetrating the mass-market price segment.
