Core Viewpoint - The article emphasizes the importance of safety measures and precautions for driving in snowy and icy conditions as the "Great Cold" season begins, highlighting the expected severe weather conditions and the need for drivers to be well-prepared. Weather Conditions - The "Great Cold" season has started, with predictions of strong winds and low temperatures across various regions, including Dalian, Fuxin, and Chaoyang, where temperatures may drop to between -30°C and -24°C [1] - Wind chill effects are expected to be significant, urging individuals to pay attention to weather forecasts and prepare for extreme cold [1] Driving Safety Tips - Drivers are advised to check their vehicle's wipers and ensure they are functioning properly before heading out [2] - It is crucial to use vehicle lights appropriately, including headlights and hazard lights, to enhance visibility [2] - Due to slippery road conditions, drivers should reduce speed, increase following distance, and avoid sudden maneuvers to prevent accidents [2][3] Vehicle Features - Drivers should utilize safety features such as TCS (Traction Control System) and ESP (Electronic Stability Program) to enhance vehicle stability and prevent skidding [4][5] - The ABS (Anti-lock Braking System) should be fully engaged during emergency braking to maintain control [5][6] Equipment Recommendations - It is recommended to equip vehicles with snow chains on drive wheels to improve traction and safety [8][9] - Switching to winter tires is advised for northern drivers, as they provide better grip on icy roads compared to regular tires [10][11] Driving Techniques - Maintaining a slow speed is essential on icy roads, as higher speeds increase the risk of losing control [12] - Gentle steering and braking are critical to avoid skidding; sudden movements can lead to loss of vehicle stability [14][15] - The braking distance on icy roads can be significantly longer, with data indicating it can be over seven times that of dry roads [15][16] Emergency Preparedness - Drivers in high-cold regions should carry essential emergency supplies to ensure safety in case of being stranded due to severe weather conditions [19]

Core Viewpoint - The article emphasizes the importance of safe driving practices during winter weather conditions, particularly in rain and snow, highlighting the risks associated with low road traction and the need for caution while driving [1][2][4]. Group 1: Driving Conditions and Risks - Icy and snowy road surfaces have low traction coefficients, leading to longer braking distances and increased risks of accidents such as rear-end collisions and skidding [2][4]. - The traction coefficient for dry asphalt is approximately 0.8, while it drops to around 0.2 for compacted snow and 0.1 for icy surfaces, indicating that braking distances can be over four times longer on icy roads compared to dry roads [4]. Group 2: Safety Driving Tips - Drivers should utilize features like TCS (Traction Control System) and ESP (Electronic Stability Program) to enhance vehicle stability on icy roads [6]. - It is crucial not to rely solely on ABS (Anti-lock Braking System) for emergency braking, as it does not shorten braking distances [8]. Group 3: Misconceptions about Intelligent Driving - There are common misconceptions regarding the use of "smart driving" features in winter conditions, as drivers may not fully understand the limitations of automated driving technologies [10][11]. - Maintaining the cleanliness of vehicle sensors is essential for the effective operation of intelligent driving systems, especially in snowy or icy conditions [13]. Group 4: Specific Weather Conditions - The phenomenon known as "ice crust" can form after snowfall, creating extremely slippery conditions that significantly increase the risk of vehicle loss of control [14][15]. - Drivers should be vigilant for signs of "ice crust" on the road, such as a deepening color or reflective sheen, and adjust their driving accordingly [17][19]. Group 5: Recommendations for Freezing Rain - In freezing rain conditions, it is advisable to minimize driving and to be aware of road conditions, particularly on bridges and elevated structures where ice is more likely to form [22][24]. - Drivers should prepare for potential hazards by reducing speed and avoiding sudden maneuvers, especially in areas prone to ice accumulation [24][26].

Core Viewpoint - Tencent Cloud is accelerating the localization of database software with the launch of the TDSQL integrated version, which aims to provide a secure and efficient database solution for enterprises [1][4]. Group 1: Product Development - The TDSQL database is fully compatible with MySQL and PostgreSQL, achieving 100% compatibility with MySQL and 98% with Oracle syntax, facilitating smooth migration for enterprises [4][6]. - TDSQL, developed since 2009, has evolved to support various applications in finance and government, breaking world database performance records in 2023 [6][9]. Group 2: Market Context - Oracle has historically dominated the Chinese market with over 70% market share in the 1990s to 2010, but its high costs and performance issues have led to a push for domestic alternatives [7][8]. - The Chinese relational database market is now led by local companies, with Alibaba, Tencent, and Huawei holding 26.2%, 14.9%, and 11.1% market shares respectively, according to IDC 2023 [9]. Group 3: Strategic Initiatives - Tencent has invested in a comprehensive suite of domestic software solutions, including TDSQL, TencentOS, and various industry-specific applications, to support innovation across multiple sectors [11]. - The company collaborates with over 50 partners to create 65 replicable industry solutions, addressing the needs of finance, government, healthcare, and more [11].
