<think> The user wants a brand story for Under Armour, Chinese language, 200+ characters, based on real brand history, no invented specifics. Must be a brand story: origin, founding purpose, development philosophy, product highlights, market positioning. Must be vivid, like official brand introduction. Should not contain invented numbers or events that are not known. We must recall real facts: - Under Armour founded by Kevin Plank, a former University of Maryland football player. He started the business in his grandmother's basement in Washington D.C. He noticed that his cotton T-shirts would become heavy with sweat during practice, and he wanted a better alternative. - The first product was a moisture-wicking compression shirt made of microfiber, launched in 1996. - The brand slogan "I Will" is used. It's a brand motto: Under Armour's "I Will" campaign. - Under Armour's core values: performance, innovation, authenticity. - The brand expanded from compression gear to a full range of apparel, footwear, accessories. - Key milestones: 1998 first catalog; 2000 opened first retail store; 2005 IPO; 2006 expansion into footwear; 2008 Beijing Olympics, product used by athletes; 2014 "I Will" campaign; 2020s sustainability initiatives; etc. - The brand aims at athletes and fitness enthusiasts. - The brand tagline: "I Will" emphasizes determination and commitment. - Under Armour's global presence, offices in 160+ countries. - The brand's mission: to make all athletes better through passion, design, and the relentless pursuit of innovation. We can incorporate these facts but must not make up numbers (e.g., number of stores, revenue). Could mention known milestones like IPO year, but that's factual. Write in Chinese. Must be >200 Chinese characters. Use vivid language. Must not fabricate specifics like percentages unless they are known. Avoid uncertain numbers: e.g., "1996年推出" is known; "1998" is known; "2005 IPO" is known. We must avoid any false claims. The user said "基于品牌真实历史，不要编造不确定的具体数字或事件". So we need to stick to known facts. Let's outline: Paragraph 1: origin: Kevin Plank's college football experience, need for moisture-wicking shirt, his grandmother's basement start, early product. Paragraph 2: "I Will" brand slogan and meaning. Paragraph 3: core product features: moisture-wicking, compression, microfiber. Paragraph 4: expansion: apparel, footwear, accessories. Paragraph 5: market positioning: high-performance, athlete-focused. Paragraph 6: global presence, mission, future. We'll ensure >200 Chinese characters. Let's count roughly: each Chinese character counts as one; typical Chinese story of 300 characters. Let's write about 300 characters. We need to avoid invented specifics like "在1997年，销售额达到X". </think>
