Since its debut in January 2010, Jiangsu Satellite TV's "If You Are the One" has become the most popular TV dating show in China. Millions of Chinese viewers at home and abroad rush to watch the latest episodes aired on weekend nights.

The controversial reality show, which challenges the more traditional dating program format, features humor, conflicts, and all kinds of turns and twists. In every episode, there is a lineup of 24 female guests and five male bachelors. The female guests will learn more about each male hopeful through watching video clips and on-the-site interactions. Then they decide whether they should dismiss him by switching the podium light off. The man who survives three rounds of test will gain the right to vie for the heart of his dream girl.

The show has attracted a great number of "older singles", males and females, from across the country and abroad. More and more foreigners hoping to find their soul mates have also appeared on the show.

More than an ordinary dating showing, the program reflects the younger generation's outlook on life, values and society. That's probably one of the reasons it has been so successful. Paul Jackson, a prominent British television director, claimed the program as the best of its kind in the world.

It's said that the show has created more than 2.4 billion yuan (US$159 million) in economic returns in 2012, while some female guests garnered overnight fame through the platform.
