In October of 2016, Lay's solo career began with the release of "what U need?" as a surprise gift for his fans on his birthday. The song was ranked number one in China V Chart, as well as in "Billboard" World Digital Songs and had entered the top 60 of iTunes, making Lay the first Chinese artist to appear on the list.

On October 28, a day after holding a press conference in Shanghai Town & Country Community, Lay released his first mini-album titled "Lose Control", which contains six songs in Mandarin, and the music video for the single. Lay participated in the production of the album as a producer, and was personally in charge of the composition, arrangement and writing of the lyrics of each song, as well as the translation of the same lyrics in three other languages including English and Japanese. The single "Lose Control" remained in first place in Billboard China V Chart for six consecutive weeks.
