Xu Lijia, the Olympic champion of the women's sailing boat who has retired, recently posted a video on her personal social platform, in which she joked, "If the gold medal of the Tokyo Olympic Games will peel off, what about the London Olympic gold medal that has been stored for 9 years?" Don't dare to look..."
The reason why Xu Lijia expressed such an emotion is directly related to the London Olympic gold medal she donated to the China Maritime Museum. Xu Lijia introduced in the video that she donated most of the medals, some equipment and training diaries of her sports career to the China Maritime Museum. But when she returned to the China Maritime Museum to see her Olympic gold medal, she was shocked.
Because this originally brilliant Olympic gold medal has already had a serious oxidation situation, both front and back, have been largely oxidized to a large extent. Fortunately, after the restoration of the staff of the China Maritime Museum, the gold medal has basically returned to its original appearance.
However, according to the master, the reason why this gold medal will oxidize is because the gold content of the London Olympic gold medal is seriously insufficient, in fact, this gold medal is made of sterling silver, in order to make it look like a gold medal, but it is plated with a layer of gold on its surface, so it will oxidize. Although this restoration has restored the gold medal to its original appearance, I am afraid that it will be necessary to be happy often in the future to keep the gold medal always shining.
In contrast, the bronze medal of the Beijing Olympic Games, which hangs next to the gold medal, is intact, which is the bronze medal that Xu Lijia won at the Beijing Olympic Games. It is also an Olympic medal, and the personal experience of so many athletes is enough to see how good the quality of the medals in the Beijing Olympic Games is. The London Olympics, like the gold medals at the Tokyo Olympics, will see oxidation and discoloration in just a few years, months or even a few days.
According to Deng Linlin, a gold medalist in gymnastics at the Beijing Olympic Games and the London Olympic Games, the gold medal of the Beijing Olympic Games is full of gold, and it will leave an embossed mark when you bite it hard. After the Fire at the home of the Russian Rhythmic Gymnastics Champion Dalia of the Beijing Olympic Games, she also showed the intact Beijing Olympic gold medal, which proved the quality of the Chinese gold medal and the sincere attitude of the Chinese people to all athletes.
