I've always wondered about Jang Hao's MBTI, but I think he's INFJ

Zhang Hao's MBTI is known as INFJ, which is described as a personality type that is innately warm and has a deep inner self. INFJs have an excellent ability to understand and empathize with others' emotions, which seems to be well reflected in Zhang Hao's delicate and affectionate attitude when communicating with fans. He radiates strong charisma on stage, but he shows a quiet and calm side off stage, which seems to well display the typical two-faced charm of INFJs. Thanks to this personality, he seems to have established himself as a reliable leader when collaborating with his team members.

It's amazing how you always work hard on stage.
