The vessel successfully completed all tasks of China's 42nd Antarctic expedition mission before returning to Shanghai.

After completing the first stage of comprehensive ocean station surveys on Friday, Xuelong 2 sailed toward higher latitudes and selected a large, relatively flat piece of sea ice about 1.5 meters thick in a densely packed ice zone for its first ice station.
According to Lin Long, captain of the Xuelong 2 sea ice team, the ice station survey conducted by the vessel during this voyage will include six short-term ice stations and one long-term ice station, the Xinhua News Agency reported Sunday.
More than 20 types of scientific operations will be carried out, including the deployment of expendable ice-based buoys, snow and ice-core sampling, under-ice water sampling, sea-ice remote sensing, atmospheric profiling and under-ice oceanographic observations.
Lan Musheng, assistant to the chief scientist of the expedition, said the researchers will comprehensively monitor changes in parameters related to the atmosphere, sea ice, upper ocean and ecological processes beneath the ice as the sea ice melts.
The observations will provide scientific data for studying the rapid changes in Arctic sea ice, the mechanisms behind those changes and the evolution of Arctic ecosystems.
The ice station work is part of China's 16th Arctic Ocean scientific expedition, which was organized by the Ministry of Natural Resources. The expedition set sail from Dalian, Northeast China's Liaoning Province on July 3.
The mission is being carried out by four vessels - Xuelong, Xuelong 2, Jidi and Tansuo-3 - and is expected to be completed in early October. 
The expedition is focusing on comprehensive surveys of sea ice, hydrology, biology, ecology and the atmospheric environment in key areas of the Arctic Ocean.
The two icebreakers Xuelong and Xuelong 2 will work together on the ice station surveys. Xuelong completed surveys at 12 ice stations on Friday.
Lin said the ice station locations planned for Xuelong 2 will work in coordination with those of Xuelong to form an observation array. 
The arrangement will allow researchers to more deeply investigate the interactions among the atmosphere, sea ice and ocean in the central Arctic Ocean amid rapid environmental changes, as well as their coupling effects with the ecosystem.
The expedition is being conducted against a backdrop of rapid changes in the Arctic environment. 
When the mission was launched in July, expedition leader Wang Jinhui said that global warming was driving rapid and profound changes in the Arctic natural environment, with trends such as sea-ice melting intensifying.
The expedition is therefore designed not only to monitor environmental changes but also to investigate frontier scientific questions, including the dynamic evolution of the oceanic crust. 
Working on sea ice also presents significant safety challenges. Low temperatures and complex ice-surface conditions can pose risks to researchers, while polar bears are considered the biggest safety risk during ice station operations.
The expedition team has therefore formulated specific bear-prevention and emergency response plans and equipped personnel with various types of bear-deterrence equipment and emergency supplies to ensure their safety.

抖音直播电商业务大幅拉动了罗永浩的还债速度，2020年9月23日，罗永浩在《脱口秀大会》总决赛中更新还债进度：“始于2018年年底的6个亿的债务，到今天我们已经还了快4个亿了。等这些债务真的全部还完了之后，可能会拍一个纪录片，来纪念这一段诡异的人生旅程，这个纪录片的名字我都想好了，就叫《真还传》。

C | ”2022年6月12日晚间宣布要退网的罗永浩还在13日晚间于抖音“交个朋友直播间”进行了直播告别。但是将第一个创业赛道定为AR的老罗截至目前并未透露相关方面的进展，一位多年聚焦AR/VR赛道的创业者对记者表示，五年之后，AR消费级市场应该还没开始，但老罗进来，至少供应链和现在这一批AR硬件厂商会被刺激到，并产生一定的加速作用。罗永浩的抖音直播间将继续运作，而“起家”于抖音直播间并进行多平台探索的除了老罗还有俞敏洪。昨日，已有消息称俞敏洪将现身“新东方迅程教育专营店”淘宝直播间，讲解大学生学习成长与规划方面内容。在俞敏洪将现身的“新东方迅程教育专营店”淘宝直播间里，目前暂未透露更多信息。记者在“新东方迅程教育专营店”店铺看到，该店铺粉丝数为7.86万，售卖的产品包括英语四六级、考研、英语口语等教育产品。去年双11期间，俞敏洪首次在淘宝“直播带课”，分享大学学习、职业路径规划等，共有数万用户购买了考研英语、大学英语四六级等课程。“现在不让搞二选一，更多的还是要看主播的意愿。”有电商平台人士告诉第一财经。今年，淘宝天猫推出“品牌书课”名师直播计划，除俞敏洪外，考研界名师张雪峰、肖秀荣等已接连登陆淘宝直播，未来还有更多名师入驻。淘宝天猫正为成人在线教育提供更广阔的空间，不仅能购买辅导书籍和培训课程，还有试听试看、直播学习等教育服务。对于教育机构而言，直播是天然适合的场景。教育产品本身以内容服务为主，在直播间可以试课、解决用户对于课程产品的个性化提问。

D | 对于潜在学员而言，授课老师在直播中展示自己的教学风格、气质谈吐，可以让学员更快地做出购买决策。淘宝教育运营总监叶挺曾表示，淘宝上大量职业考试用书的购买行为背后，是对考试需求的表达，而在线课程正是对这一关联需求的满足。这种“书课一体”的模式，在供给侧将课程产品与淘宝上最普遍的实物商品结合在一起。“俞敏洪和罗永浩的加入，也许会带去流量，加上李佳琦在，淘宝直播双十一成绩应该还是可观的。不过现在直播电商也在‘去大主播’化，头部大主播的销售额背后折射出巨大的资源集中效应，中小主播及长尾主播能获得的空间被压缩。”网经社电子商务研究中心分析师莫岱青告诉第一财经记者，商家为了能够进入到头部主播的直播间，势必要做出让利和牺牲。“中小主播来到台前，加上店播的争夺，直播电商环境也在发生变化。

E | 另外头部是可以培养的，没有薇娅，也会有其他人出现。” 莫岱青认为。
