The meaning behind his stage name is that the number 8 is considered a lucky number in China and when the 8 is laid down, the infinite sign appears, symbolizing infinite luck.
His real name Xu Ming Hao, can be interpreted as 'Bright and Prosperous'.
He was the last member to join the group.
He has been practicing Chinese Martial Arts since he was 5 years old. He participated and won first prize at the National Children’s martial arts competition.
He did b-boying in China for 6 years.
His role models are his parents.
Being from China, he wasn't fluent in Korean and had to fend for himself, so he often buried his face in his pillow and cried a lot. He relied a lot on Jun & Hoshi. He said these two made it possible for him to debut as SVT member.
His first meeting with Jun didn't go very well because Jun had mistaken him for someone else (Jun's friend whose name was also Minghao), but is now considered a very embarassing first impression story on Jun's side.
He is a Christian and Buddhist.
He wanted to be a superstar since he was young. He got into an audition at school when he was in China.
He said he watched a lot of variety shows when he was in China and he wanted to be a superstar, so that’s why he became a singer in Korea.
His role model is Henry. He is Chinese and really works hard and efficient. He wants to be like him.
He always makes sure to eat his meals without skipping any. Even if he has to wake up at 3 AM, he would wake up 1 hour before and eat.
Between Korean food and foreign food, he prefers Chinese food. He and Jun know almost all the Chinese restaurants in the city, and often recommend certain places to the members when they are going to eat Chinese.
He likes melon.
He says Mingyu is his soulmate as they click.
He is the one who always give birthday gifts to the members.
He created and is part of a group chat with other Chinese idols who work in Korea, including Jun, WayV's Kun, and Pentagon's Yanan.
He's one of the most artistic members, alongside Mingyu, even saying to establish a fashion brand called "MM" together in the future. He likes painting & photography.
He is SEVENTEEN's fashionista. He says he can freely express himself through fashion, and he feels like he's truly living as himself when he has a great outfit on
He began to paint when he took a break in 2017. At that time, he felt a little suffocating so he began to try new things to escape from that feeling
He hangs out with Mingyu's dad a lot (even without Mingyu sometimes). Since his parents live in China, he might feel lonely at times, so Mingyu's dad once told Minghao to treat him as his second father. He also often assists Minghao when he needs help in daily life. They even went fishing together.
He has a small series of projects called, "The8's Contemporary Art".
He and Mingyu, DK, BTS Jungkook, Astro Eunwoo, GOT 7 BamBam, and NCT Jaehyun are good friends due to sharing the same age, also having a group chat named "97 Liners" between them.
