In just two months, the latest buzzword from the Internet, diaosi, has spread so much that it can be found everywhere—from online forums(论坛) to micro blogs. Many people even call themselves diaosi. It’s not the first time a term has gone popular on the Internet in China. However, why is the word so viral that is has become a cultural phenomenon? Here, we tell you something you want to know about it.

Where it began

The word originated in Baidu. Com’s Tieba (a top Chinese bulletin board system) of soccer player Li Yi. There, fans of Li, who are called yisi in Chinese, not only talk about soccer but complain about their lives, work and relationships. Yisi, who are known for their rude and dirty language, were given the name diaosi by others who have seen their posts.

What a “diaosi” is like

The word diaosi was coined first by single, young men who feel they have dead-end lives. Generally, men in this category don’t earn enough, are not good-looking, and have difficulty winning promotion(晋升). Unlike their upper-class contemporaries(同代人), they lack influential families, useful social networks for their careers, and most importantly, suitable women to marry. “I’m just a diaosi, poor and plain-looking. Who will marry me?” The sigh can be heard, which is half self-mockery(自嘲), half reality. Many young men call themselves diaosi because they feel they are among the lowest classes of the society.

“Diaosi” culture reflects social changes

According to Zhu Chongke, a professor in the School of Asia-Pacific Studies at Sun Yat-sen University in Guangzhou, the popularity of this word diaosi stems from the fact that is was created by common people and thus resonates(共鸣) with a huge population. “Labeling yourself a diaosi offers a way for people to mock themselves and relieve pressure, hence it spread quickly,” he told Xinhua Agency. “The attitude is basically: ‘I already have little to lose, so why don’t I mock myself for gun?’.” The phenomenon reflects a larger social issues. These young people have no influential family background, no chances of receiving promotion at work or no economic strength to find a proper woman to marry. It reflects a deep sense of loss.
