Rio 2016: A personal journey through China's Olympic history

China's fortunes have been turned on their head in Rio

As another Olympic Games draws to a close, BBC Chinese's Yuwen Wu makes a personal journey through China's Olympics of the last few decades.

There is no doubt that one of the talking points of the Rio Games has been China's performance. The country lies third in the medal table, behind the USA and Great Britain, making it China's worst games since 2004.

In events in which it is traditionally strong - such as gymnastics - China performed miserably, and fell short in swimming and badminton too.

So what has gone wrong? I look at it another way: the very fact we are asking this question shows just how far China has come.

Despite Team China's troubles, medal-winning swimmer Fu Yuanhui won fans around the world for her expressions and her honesty

Los Angeles 1984: Fighting for one's country

After decades of political wrangling, China finally participated fully in the world's greatest sporting spectacle.

At home in Beijing, we had got our first colour TV, which became a focal point for the whole family as we watched the Chinese sporting heroes competing with some of the best in the world.

When Xu Haifeng won China's first ever Olympic gold medal, in pistol shooting, it was hailed as a "great breakthrough" and the whole nation celebrated.

China went on to win 15 gold, eight silver and nine bronze medals at those Games, finishing fourth in the medal table. Gymnast Li Ning, with three gold, two silver and one bronze medal, became an instant celebrity.

I still remember the women's volleyball final with the USA. China were already world champions and the players were household names.

They had lost to the USA in the preliminary round, but beat the USA 3-0 in the final. The match was tense, made worse by my over-enthusiastic neighbour, who constantly shouted out latest scores through his window for all to hear.

It was a time of great optimism, not only for sport, but for China's development too, as the country finally shook off the shadow of the Cultural Revolution and embarked on reform.

What's more, China's presence at the 1984 Games made the world sit up and notice.

Seoul 1988: War on doping

China was not able to replicate the feat four years later in Seoul, managing only 11th place in the medal table, with five gold, 11 silver and 12 bronze medals.

This was partly blamed on the strong performance of the Soviet bloc countries, back from their Olympic boycott.

Zhong Huandi, who competed in the Seoul Games, was one of China's most successful long-distance runners

But for a lot of people, the Seoul Games were remembered for one person: Ben Johnson, the Canadian sprinter who tested positive for a banned substance after he came first in the 100m final.

I was studying at the University of Toronto and witnessed first-hand the shock of the nation as euphoria turned to nightmare. I became aware of the issue of doping in sport for the first time, not anticipating that China was soon to have its own doping scandals.

At the 1994 Asian Games in Hiroshima, Japan, 11 Chinese athletes tested positive for steroids - seven of them swimmers, including world champions. They were stripped of their medals and banned for two years.

About the same time, a group of female long-distance runners caught the world's attention. Coached by Ma Junren, these athletes consistently broke Chinese, Asian and world records, accumulating three gold medals in the 1993 World Athletic Championships and one gold in the Atlanta Olympic Games in 1996.

Ma was known to be a very tough coach to his athletes, known as Ma's Army

In 2000, most of Ma's runners failed blood tests and were banned from the Sydney Games that year.

Early in 2016, a letter reportedly written by leading runner Wang Junxia and nine others, came to light, with detailed revelations about how Ma had forced them to take drugs to boost their performance. The International Association of Athletics Federations (IAAF), which governs athletics, has indicated it will investigate the matter.

These episodes and others seriously tarnished China's image. Despite a crackdown and an improved testing regime, the battle is far from won - as shown by swimmer Chen Xinyi, who was forced to leave Rio after testing positive for performance-enhancing drugs.

Beijing 2008: Politics and sport

The Beijing Games were a spectacular in which China took enormous pride

In 2008, Beijing hosted the Olympic Games, a matter of tremendous national pride. Politics and sport had never been so closely linked.

China wanted to showcase not only its sporting ability, but also how the country had been transformed by three decades of opening up and reform.

The Beijing Games divided opinion perhaps more than any other in post-war history, and as a journalist working in London, I have to admit I breathed a sigh of relief when they were finally over.

In sporting terms, China scored a great victory by coming top of the medal table, taking home advantage to the full.

Liu Xiang was China's most celebrated track star

By now, China was a recognised global sporting power. But things were not perfect. China's only medal hope in athletics, hurdler Liu Xiang, pulled out of the race due to injury, and the lack of transparency surrounding his injuries angered his fans and raised questions about commercial pressures put on elite athletes.

London 2012: Questions continue

Liu Xiang almost repeated the fiasco during the London Games four years later, this time crashing out at the first hurdle. His agonising pain was for all to see, but he managed to hop with one foot to the finishing line, to huge applause by a very appreciative crowd.

Other competitors showed class, too, by praising his spirit, one of the most heart-warming moments of the London Games.

While some Chinese fans have been critical of their sportsmen and women, others have been more supportive

Now, back to Rio. What has gone wrong with China's sportsmen and women?

Rio 2016: Winning is no longer everything

One explanation offered is the lack of new, world-class talent. I watched some gymnastic competitions on TV and I have to admit that, compared with others, Chinese gymnasts lacked power and artistry. But there might be other reasons.

Fu was delighted with her bronze medal

Compared with 1984, when winning a gold medal was a political task and a patriotic duty, or with 2008, when more medals meant more national pride, we are seeing a more relaxed attitude.

While people still like to see China doing well, it perhaps no longer carries the importance it once did - although we have seen our share of soul-searching.

"As long as you gave your all, you're already a winner", Chinese netizens told bronze medallist Fu Yuanhui, who won hearts around the world with her expressive joy and honesty about competing during her period.

Could it also be that China, the world's second largest economy and more confident on the international stage, no longer needs to take winning in a sport event, however noble and inspiring, so seriously?

Who knows? Perhaps a more relaxed approach will help China produce more medals in the future. So UK and USA, watch out!
