Singer-songwriter who trained as a nurse and won the 2017 talent show 明日之子 with songs of his own; 消愁 made him known overnight. He writes plain, quiet ballads about everyday life.
He picked his stage name as a teenager: 毛 comes from his childhood pet name 毛毛, and 不易 is meant not as everyday 'not easy' but with 易 in its older sense 'change': a promise not to change easily.
