In May last year, Zhao Yunlei, the Olympic champion of Chinese badminton, defended her doctoral thesis and became the first Olympic champion doctor in the history of Chinese badminton. Today, the Korean badminton world has also ushered in a champion doctor, and the world champion Sung Ji Hyun successfully graduated from the Korea Sports University and completed the master's and doctoral degrees. Sung-hyun wrote thanking the professor for his guidance and confessing that he had always supported his family, specifically mentioning her husband, Sun Wanhu.

After receiving his diploma, Sung Ji-hyun took a group photo with his family and friends to record this beautiful moment. In the photo, Sung Ji Hyun put on a bachelor's uniform, holding a graduation certificate and flowers, and showed a bright smile to the camera. Seeing that the former Korean badminton sister turned into a school bully, many fans have sent blessings and praised her as "the winner of life with three harvests of career and academic love".
Sung-hyun was born into a badminton family in South Korea, her parents were famous Korean badminton players, and her father was later invited to serve as the coach of the badminton national team. Under the influence of his parents, Sung Ji Hyun showed his talent in badminton from an early age, and became a leader after entering the national team. Her highlight was the 2017 Sudirman Cup, where Sung Ji-hyun and his teammates fought all the way through the thorns and won the championship as a "dark horse".
Due to her high appearance and the daughter of a famous Badminton couple in South Korea, Sung-hyun gained the nickname of "Princess Cheng". In her days on the South Korean badminton team, Sung-hyun was the brightest star, and her world ranking once broke into the top three, which was enough to prove her talent and strength. However, as she grew older, Sung-hyun's status gradually declined, and she eventually lost to the Tokyo Olympics, after which she faded out to focus on her studies.
It is worth mentioning that the beautiful love between Sung-ji-hyun and Sun Wanhu, the former brother of the Korean feather court, has always been talked about. The two were related to badminton, and because they often went abroad to participate in competitions together, their relationship progressed rapidly. On December 12, 2020, Sung Ji Hyun and Sun Wanhu ended their love run and held a grand wedding, becoming another world champion couple in badminton. Sun Wanhu's career has also been brilliant, winning the gold medal of the men's team at the 2014 Asian Games, the third place of the 2017 World Badminton Championships and the sudirman Cup.
Although he retired from the national team after losing the Tokyo Olympics, Sun Wanhu did not stop his playing career, and his future plan is to participate in domestic competitions as a member of the government team, and if there is corporate sponsorship, he will participate in international competitions in his personal capacity and continue his badminton dream. After Sung-hyun quit the national team, she spent more time on studying, and now that she has successfully obtained her diploma, it is indeed a congratulatory thing for her.
