　　One of the hottest buzzwords in China right now is no doubt tuhao, a sarcastic, light­hearted term referring to rich people of little education, bad taste or lacking self­awareness.

　　This is yet another example of smart Chinese Internet users applying their creativity to an aged phrase and giving it new life and meaning. The term, which literally means "country bully"， has been around since ancient times, when it was used to refer to rich and powerful rural and lords.

　　However, the meaning of the word changed significantly when it was adapted a few years ago by Chinese players of the wildly popular computer game "World of Warcraft" to refer to rich players who spend big money buying powerful virtual weapons. Because they don't improve their skills by playing, these players are considered silly, uncultured, and unprofessional.

　　But that is not the end of tuhao's new life story. The renewed popularity of the term also coincides with (同时发生) the emergence (出现) of the Chinese "nouveau riche" - a generation of businessmen and women, property owners and entrepreneurs who have rapidly accumulated large amounts of wealth in recent years.

　　Similar to the many rags­to­riches stories in human history, many Chinese billionaires who are on the global rich list do not come from well­educated or prestigious (声望很高的) backgrounds. Rather, they achieved financial success through powerful connections, smart investments, and by riding out China's economic boom. Many of them don't shy away from throwing their money around, yet we are often reminded of their lack of manners, taste and cultural sensitivity.

As a result, a term that was popularized in the gaming world has now also been introduced into daily conversation.
