Collaborative empirical research among these areas will make new contributions to evolutionary linguistics, both in breadth and depth. The International Conference in Evolutionary Linguistics (CIEL) was initiated by Professor WANG S-Y. William. Through CIEL, we wish to promote international interaction and boost interdisciplinary collaborations. Previous CIEL conferences in Guangzhou (2009), Tianjin (2010, 2015), Shanghai (2011, 2019), Beijing (2012), Xiamen (2014), Indiana USA (2016), Kunming (2017), Nanjing (2018), Lanzhou (2021), Jinan (2022), and Hong Kong (2013, 2023) were all held in the same spirit.15th International Conference in Evolutionary LinguisticsCeremony
