Alibaba plans to split itself into six independently run companies that could seek separate IPOs.The reorganization of one of China's largest private-sector businesses—once valued at more than $800 billion but now worth about a quarter of that—effectively dismantles a business empire Jack Ma built over two decades，just as the entrepreneur reappeared after months overseas.Ma stepped down as Alibaba executive chairman in 2019.He has kept a low profile since a speech in 2020.This week，he returned to Alibaba's headquarters city of Hangzhou.Ma didn't immediately respond to requests for comment sent through his eponymous foundation and Alibaba. 阿里巴巴计划将自己拆分为六家独立运营的公司，这些公司可能会寻求单独的IPO。中国最大的私营企业之一的重组——曾经估值超过8，000亿美元，但现在的价值约为四分之一——有效地瓦解了马云20多年来建立的商业帝国，就在这位企业家在海外数月后重新出现时。马云在2019年辞去了阿里巴巴执行主席的职务。自2020年的一次演讲后，他一直保持低调。本周，他回到了阿里巴巴的总部城市杭州。马云没有立即回应通过其同名基金会和阿里巴巴发出的评论请求。
