In 2016, he signed a contract with a Taiwanese brokerage company, but as he did not get the training promised when signing the contract, he and the other members held a press conference at the door of the company to complain. After that he passed the Shanghai Banana Entertainment global trainee audition, signed a contract with Banana Entertainment and officially became a Banana Entertainment trainee.
