Stories behind a precious photo

Who are they in this photo (Figure 1)? When and where was this photo shot? As shown by the background you may see, it was taken at the 16^th World Conference on Lung Cancer (WCLC) which was successfully held between 6 and 9 September, 2015. In this great photo are the Co-Editor-in-Chief, the Guest Editor, as well as 15 authors of the journal Translational Lung Cancer Research (TLCR). They all gathered together because of a focused issue themed as “Improving the Quality and Outcomes of Lung Cancer Care: An Interdisciplinary Approach”, which was published in the 2015 August Issue of TLCR (Vol 4, No 4).
