Which ex-EXO member upset K-pop fans when he went on a TV rant about BTS?

The famous Chinese celebrity was told he looked like a BTS member, angering fans when he dissed the rival K-pop group
Chinese celebrity Huang Zitao, a former member of the K-pop boy band EXO, has angered BTS fans when he was mistakenly identified as a BTS member by visitors in China.
On a Chinese entertainment show, the Chinese star from Qingdao, better known in Korea as Tao, approached four French women on the street. He wanted to see if they recognised him as a former K-pop star, a singer and an actor in China.
Their initial encounter was followed by his offer to take a picture together with the women.

Then the former SM Entertainment member started ranting at a camera crew filming the scene.
“Edit this part out,” Tao said. “They said I looked like a BTS member. I know EXO but don’t know about BTS.”
The embarrassed star, who walked out from EXO in 2015, kept saying, “BTS back then was less popular than EXO, and now people say to me I am a BTS lookalike. Sorry, I have just become a BTS member by someone.”
