In 2014, during the Beijing APEC meeting, measures such as traffic restrictions and suspension of polluting industries were implemented in Beijing-Tianjin-Hebei to ensure good air quality. After experiencing three bouts of smog in a month, Beijing's air quality reached level one (excellent) on November 3rd, a phenomenon dubbed the "APEC Blue". In 2013, the number of days with good air quality in Beijing accounted for only 47.9\%. In the first half of 2014, with a 30\% reduction in emissions, the number of days with good air quality increased by 20 days compared to the same period in 2013. To achieve the target of increasing the number of days with good air quality by 20\% for the entire year, how many more days with good air quality are needed in the second half of the year compared to the same period in 2013?
