“逢凉野性”是易烊千玺为自己的17岁生日会原创的主题名。“逢凉就是指自己有严肃的一面，而野性又展现出另一种极端的风格，多样的易烊千玺。”
Jackson Yee personally explained the theme Coolness Meets Wildness during a media interview before his 17th birthday concert in Beijing on November 28, 2017.
In his own words:"Coolness stands for my serious side, while wildness represents another extreme style. Combined, they show the diverse sides of me."
