Core Viewpoint - The "Ao-Tai Line" is a popular trekking route that poses significant dangers due to extreme weather conditions and illegal crossings, leading to numerous fatalities over the years [1][9][12]. Group 1: Dangers of the Ao-Tai Line - The Ao-Tai Line connects two major peaks in the Qinling Mountains and is known for its beautiful scenery, which attracts many hikers despite the risks involved [1][2]. - The region experiences complex weather patterns due to the convergence of cold and warm air currents, leading to sudden and severe weather changes such as fog, thunderstorms, and blizzards [4][6]. - High-altitude conditions result in significant temperature drops, with nighttime temperatures in winter plummeting to -20 to -30 degrees Celsius, creating life-threatening situations for unprepared trekkers [8][10]. Group 2: Incidents and Regulations - From 2012 to 2017, there were over 50 reported fatalities due to illegal crossings of the Ao-Tai Line, highlighting the dangers of disregarding regulations [8][12]. - In 2018, an official announcement was made to prohibit all unauthorized access to the Ao-Tai Line, emphasizing the need for safety and adherence to rules [9]. - Recent incidents have shown that some groups attempt to evade monitoring by disabling their phones, complicating rescue efforts when emergencies arise [10][11]. Group 3: Public Perception and Environmental Impact - The Ao-Tai Line is often referred to as a "graduation line" among outdoor enthusiasts, symbolizing a rite of passage, which may encourage reckless behavior [12][15]. - Illegal trekkers often leave behind non-biodegradable waste, causing irreversible damage to the local ecosystem, and the resources spent on rescue operations represent a significant waste of public resources [15][16]. - The rise in outdoor activities has led to increased interest in trekking, but it is crucial for individuals to respect nature and follow regulations to ensure their safety and the preservation of the environment [16][17].
