• intros：{"brand_intro":"北京提琴厂成立于1950年，是中国最早的提琴及配件制造国企，后改制为股份制企业。品牌以\"国产性价比之王\"著称，核心优势在于长白山云杉资源独家供应和传统手工雕刻技艺。创始人陈师傅（已故）曾参与中国第一把低音提琴的制造。品控理念为\"让中国乐手用得起好梁\"，每根梁出厂前需经过48小时恒温恒湿测试。","product_intro":"该产品定位国产中高端市场，核心卖点是长白山高寒云杉（年轮密度8-10圈/cm）与手工雕刻的结合，音色温暖饱满，适合古典和民族音乐演奏。相比进口产品，价格仅为Kürschner的40%，但低频清晰度稍逊。适用场景包括音乐学院教学、业余乐团及个人练习。","key_specs":{"木材种类":"长白山云杉（Picea koraiensis）","年轮密度":"8-10圈/cm","含水率":"8%-10%","适配琴型":"3/4 至 4/4 低音提琴","雕刻工艺":"半手工雕刻（机械粗雕+手工精修）","重量":"约90g"}}
