【明報專訊】PRESIDENT XI JINPING has paid his first visit to Wuhan, Hubei, a region profoundly stricken by the epidemic to inspect the work on controlling the disease. For four days in a row, the mainland has recorded merely two-digit numbers of confirmed cases. With the exception of Hubei, all the provinces and cities have not recorded a single case of local infection for three consecutive days. Xi's visit to a city on the frontline of the outbreak is a mark of the mainland's success in its anti-epidemic fight at this stage.
