In March 2020, the Tokyo Olympic Games were postponed, and international Olympic Committee (IOC) President Bach encouraged athletes around the world: "No matter how long this dark tunnel is, we will walk through the end together, and the Olympic flame is the light at the end of the tunnel." On August 8, 2021, the Tokyo Olympic Games came to a successful conclusion, Bach said: "Sport unites all forces, like the light at the end of the dark tunnel, giving us the hope to continue to move forward." "What the Tokyo Olympics have left to the world is not only the wonderful process of 339 gold medals, but also the positive energy at the end of the tunnel that brings the world the positive energy to fight against the epidemic when the new crown pneumonia epidemic is still raging. Three days before the Tokyo Olympics, the IOC added "more solidarity" to the Olympic motto. Under the banner of the Olympic Rings, "more unity" has entered reality from the motto. Shot put star Gong Lijiao participated in the 4 Olympic Games and finally fulfilled her dream of winning the championship, and her old rival, New Zealand's Adams, embraced her for the first time. The Chinese team's Guan Chenchen won the gymnastics balance beam event, and the bronze medal-winning American Famous Biles smiled and walked toward Guan Chenchen to hug and express congratulations. In the men's high jump final, Qatar's Bashim and Italy's Tambari scored equally, and in the event that both failed to successfully challenge the new heights, the referee asked them whether they could decide the winner through the play-offs. Bashim asked if there could be two gold medals? After receiving a positive answer, the two athletes burst into tears of joy and stood on the highest podium together. After the postponement of the Olympics, they believe that it is more meaningful to share success than to compete in a showdown. Zhang Yufei, the Chinese "female flying fish" who won 4 medals, met the host athlete Chi Jiang Lihuazi who almost bid farewell to the swimming world because of leukemia on the field, and the former competitors embraced each other deeply, and Zhang Yufei agreed with the other party to see each other next year at the Hangzhou Asian Games. Chen Qingchen / Jia Yifan lost to the Indonesian team in the badminton women's doubles final Polly / Lahayu, the 33-year-old Polly fell to her knees and cried excitedly, and the Chinese team took the initiative to support the opponent, congratulating and telling the other party to be happy when they won the championship. This light, in addition to "faster, higher, stronger, more united", but also never give up even if it fails, and the global sports arena to help each other. Defending champion Chinese women's volleyball team suffered 3 consecutive defeats in the group stage and failed to qualify for the top 8, head coach Lang Ping asked the whole team to walk out of the arena even if they lose, because the Chinese women's volleyball team represents a kind of sportsmanship. After that, the Chinese women's volleyball team won the last two consecutive games 3-0, as Lang Ping asked, and ended the Olympic journey with its head held high. Since the last Olympic Games, refugee delegations have officially made their debut. At the Olympic Games, the size of the refugee delegation increased from 10 in the previous olympic games to 29 people. With more than 25 million refugees worldwide as of mid-2020, the IOC aims to draw the world's attention to refugee issues through the Olympic movement, according to UNHCR. 12-year-old Hendzaza, the youngest table tennis player in Olympic history, is from Syria and has added many uncertainties to her path to table tennis after years of war. Still, Zaza remains passionate about table tennis, as competing in the Tokyo Olympics has become the "light" she will stick with, and she looks forward to her chance to achieve better results at the 2024 Paris Olympics three years later. The Chinese Olympic Committee invited zaza to train in China after learning about zaza, and if all goes well, she will make the trip in September. In the special context of the epidemic, the Tokyo Olympics are destined to go down in history with their particularity. Gold medals are important, but the brilliance of humanity on the road to chasing gold medals is even more moving. The Olympic Games are not only gold medals, but the Olympic spirit displayed by athletes on the Olympic field has injected a shot in the arm for the world to defeat the epidemic. That's the power of sport, and this summer we've finally waited for "that light."
