After graduating in 2014, he returned to China to establish the brand YIRANTIAN. YIRANTIAN portrays a group of independent women who pursue quality of life and have a strong attitude. They are not attached to trends, have nostalgia for the classics, but understand and accept the current state of things. They focus on quality of life, and are elegant, refined, and sexy.
