2019-nCoV: Why I did not mask my mouth earlier? A man lived in Wuhan’s answer为什么我不早点戴上口罩预防新型肺炎：在武汉居住者的回答
I took public traffic (metro systems and train) and left Wuhan on 22th Jan morning.
Almost everyone had worn masked as well as myself. The authority issued an order
which require everyone must wearing mask at public area at night and issued “a public
transportation ban” the next day.
1月22号我按原定计划乘坐地铁与公交车离开了武汉，路上绝大部分人都戴着口罩，包括我自己。当天晚上，市政府发布《关于在公共场所实施佩戴口罩有关措施的通告》；第二天，武汉市政府宣布关闭本市所有公共交通，包括火车站。
