On August 21, Gan was invited to give a talk on the ‘大气污染的健康效应和防控措施高级研修项目’ in Xinxiang (新乡）which was organized by Henan Normal University as a special training course supported by  人社部。The title of his talk was ‘Progress in research on HAPs and its management in China’ （有毒有害大气污染物（HAPs）及其管控研究进展）.  It was my second visit/talk to/in Xinxiang this year (last time on May 24). I was very happy to see many garnet trees with fruits on on the campus of Henan Normal University, and afterwards educated by Xaofei that it has been the city tree of Xinxiang! 

Another talk in August!
