In an interview with News1 on February 13, Joo Ji Hoon talked about Netflix's 'Kingdom,' and the spread of Korean culture. While on the topic, Joo Ji Hoon mentioned BTS and gave them high praise for what they've done for the country and how they've played a vital role in spreading Hallyu (Korean wave).
The actor stated, "They're unbelievable. They've already received many awards but they really deserve more awards." He continued, "Korea is still not very well known to the world. They're many people who only think of China and Japan when they think of Asia but they're bringing an incredible economic effect (through Hallyu)."
