What is the meaning of the ”torn Taegeukgi” on President Lee Jae-myung's chest? = South Korea

On the 5th, the day after he was inaugurated as the 21st president of South Korea, President Lee Jae-myung, who presided over his first Cabinet meeting, attracted attention when he was wearing a torn Taegeukgi badge on his chest.
On that day, the president wore a Taegeukgi badge with what appeared to be a cut-off corner on the left side of his chest. This was a replica of the Taegeukgi at Jingansa Temple and was a gift from National Assembly Speaker Woo Won-sik.
At a luncheon to celebrate the inauguration of the president, held at the National Assembly reception facility the previous day, Chairman Woo Won-sik said, "Now is a critical time for us to properly establish the identity of our nation," and
The badge was attached directly to the collar of the leader. The "Jingwan Temple Taegeukgi" was discovered on the inner wall of the altar during the dismantling and reconstruction of Chilseongak at Jingwan Temple in Eunpyeong-gu, Seoul on May 26, 2009.
The Taegeukgi, which is believed to have been hidden by a monk, was wrapped in newspapers such as the Korean Independent Newspaper and the Independent Newspaper at the time of its discovery. The pattern on the Taegeukgi is also different from the usual one.
The flag is painted with ink over the Taegeuk and Shigua patterns, expressing anti-Japanese sentiment to the fullest. It was designated a national treasure in 2021.
The National Heritage Administration said, "This is the only and oldest example of the Taegeukgi painted on top of the Hinomaru flag.
"It has a great symbolic meaning in the history of the independence movement," he explained. The top left corner is burned and damaged, and there are also traces of multiple holes. For this reason, the corners of the badges that imitate it are also crushed.
Based on these characteristics, the National Heritage Administration believes that the Taegeukgi at Jingansa Temple "is highly likely to have been used at the time of the March 1st Independence Movement or at the site thereafter."
Chairman Woo posted on Facebook on the same day, "After lunch with the leaders of the ruling and opposition parties to commemorate my inauguration, I decided to hold a press conference to commemorate the March 1st Movement, with the understanding that now is the time to properly establish the country's identity.
"The badge is a replica of the Taegeukgi that was used at the time of the 1980s and is owned by Shinkanji Temple," he said. According to him, the president welcomed the badge, calling it a "meaningful Taegeukgi." President Lee also spoke on the 4th,
On February 28, just before the 106th March First Independence Day, Chairman Woo hoisted the Taegeukgi flag of Jinkansa Temple on the wall of the National Assembly and held a meeting with the descendants of independence activists.
