再次见到卿斯汉教授是在北京科协和北京计算机学会举办的“信息网络安全技术”学术报告会上,他作完报告后马上又赶往铁道部出席铁道部网络安全论证会议,此后他又要飞往新疆出席另一个会议,之后还要参加部委级的几个审定会……总之,卿教授给人的印象一直都是在为工作繁忙劳 Once again, Professor Qing Shihan was present at the “Information Network Security Technology” academic report held by the Beijing Association for Science and Technology and the Beijing Computer Society. After completing his report, he immediately rushed to the Ministry of Railways to attend the meeting of the Ministry of Railways’ cyber security demonstration. It is necessary to fly to Xinjiang to attend another conference, and afterwards, to participate in several validation meetings at ministerial level... In short, the impression given by Professor QING has always been that people are busy with work.
