2. Create a new table in Hive based on predefined data analysis dimensions and insert exported offline data into the new table.

3. Source data are preprocessed for fields such as Gender, Age, Year, Sport and Medal, including null value filling, integration of synonymous fields and elimination of invalid fields.

4. Based on data display requirements, relevant fields are grouped, aggregated, and de-weighted to provide data support for visual analysis.

What are the advantages of the Chinese team? Data speaks for itself

In the 37 years from 1984 to 2021, China has witnessed continuous development of sports, with the Chinese delegation participating in more and more diversified Olympic sports.

So many Olympic projects, which belong to the Advantage of the Chinese delegation? We have carried out statistics on the number of Chinese champions under various categories of Olympic events.

According to the statistics, the number of Olympic champions in seven categories, including diving, weightlifting, volleyball, gymnastics, table tennis, badminton and shooting, all exceeded 20, making it into the top seven. It can be seen that the results of our data analysis are quite consistent with the conventional cognition of the public.

China has achieved a breakthrough of “zero” gold MEDALS in 21 major Olympic sports

While maintaining the competitiveness of these competitive events, China’s Olympic cause has blossomed in an all-round way. After 10 Olympic Games, The Chinese delegation has achieved a breakthrough of “zero” gold MEDALS in 21 Olympic categories.

Among them, the 1984 Los Angeles Olympic Games, the first Olympic Games in which China returned to the Olympic Games, was the one in which China achieved the largest number of “zero” gold MEDALS in Olympic events. At the 2008 Beijing Olympic Games, the Chinese delegation achieved a breakthrough of “zero” gold MEDALS in five major Olympic events, such as trampoline, sailing, boxing, archery and rowing. It was also a fruitful session.

Women never let men! The rise of female power in China’s Olympic team

The number of women athletes in the Chinese delegation has consistently outnumbered men since Barcelona in 1992, with the exception of the 2008 Beijing Olympics, when the number of women athletes was slightly lower than the number of men, the data showed. In Tokyo 2021, the ratio of male and female athletes in China’s delegation is even more obvious: China sent 431 athletes, including 298 female athletes, accounting for nearly 70 percent of the total, more than twice the number of male athletes.

The analysis also showed that women accounted for more than half of China’s Olympic champions, or 64 percent. ** By the end of the 2021 Tokyo Games, 184 female athletes from China have become Olympic champions, far outnumbering their male counterparts. In this year’s Tokyo Olympic Games, the three gold MEDALS of The Chinese Olympic Team on the first day were all won by women: Yang Qian, champion of women’s 10m air rifle, Hou Zhihui, champion of women’s 49kg weightlifting, and Sun Yiwan, champion of women’s epee. Chinese girls are amazing!

The age of 24 is the prime age for athletes, with the biggest gap between gold MEDALS being 30 years

A comprehensive analysis of the ages of Chinese Athletes when they won MEDALS shows that Chinese athletes won the most gold MEDALS and MEDALS at the age of 24. From this point of view, 24 is the golden age for Chinese athletes.

When comparing the maximum and minimum age of Chinese athletes winning Olympic gold MEDALS, we found that the age difference of Chinese Olympic champions “winning gold” was up to 30 years old! At the 2004 Athens Games, 43-year-old Chinese shooter Wang Yifu won the men’s 10m air pistol title, making him the oldest Chinese Olympic gold medalist. Fu Mingxia, China’s diving queen, set the record for the smallest age to win a gold medal in the Olympic Games. Fu Mingxia won the gold medal of women’s 10-meter platform at the 1992 Barcelona Olympic Games at the age of 13, creating a world diving legend.

Wang Yifu participated in the Olympic Games for the most times, and the shooting athletes have a longer career

Statistics show that a total of 30 athletes have participated in more than three Olympic Games. ** Wang Yifu, the “Godfather of Chinese shooting”, has participated in the most Olympic Games, taking part in a total of six games and winning two gold MEDALS.

Looking at sports events, we find that shooting athletes have the largest number of “going to the Olympics” for many times. This reflects the fact that shooters have longer careers than athletes in other Olympic sports.

Twenty-one athletes have won at least three gold MEDALS, and four Chinese athletes are tied for the most Olympic gold MEDALS

By analyzing the number of gold MEDALS won by each athlete, we found that there are 21 Chinese athletes who have won at least three Olympic gold MEDALS by 2021 in Tokyo.

The athletes with the most gold MEDALS are Wu Minxia, Chen Ruolin, Zou Kai and Ma Long, who have all won five Olympic gold MEDALS. It is worth mentioning that Ma Long, the captain of China Table Tennis team, won two gold MEDALS in men’s table tennis singles and men’s team in the Tokyo Olympic Games this year, and won five gold MEDALS in total, successfully occupying the Top position in the Olympic gold medal list of Chinese athletes.
