The Fierce Wife, or in Singapore, The Shrewd Wife (Chinese: 犀利人妻; pinyin: Xīlì Rénqī) is a 2010 Taiwanese drama starring Sonia Sui (隋棠), James Wen (溫昇豪), Chris Wang (王宥勝) and Amanda Chu (朱芯儀). It was a TTV (Taiwan Television) (台視) and Sanlih E-Television (SET) (三立) co-presentation, and was directed by Xu Fujun (徐輔軍). The filming started in October 2010, and was first broadcast on 5 November 2010. It’s been on the air ever since.

Before The Fierce Wife was produced, both Sonia Sui and Wen Sheng Hao had acted in two TTV productions, The Year of Happiness and Love (那一年的幸福時光) (2009) and PS Man (偷心大聖PS男) (2010). The Fierce Wife, The Year of Happiness and Love, and PS Man all feature youth idol.

On 9 June 2011, The Fierce Wife, described as “the most talked about TV show in Taiwan,” entered the Japanese market, renamed Does Marriage Guarantee Happiness (結婚って、幸せですか). It was broadcast on BS Nittele (BS日テレ) in Chinese with Japanese subtitles, every Thursday at 2300 in high definition (1080i), six times as high as in Taiwan. The whole TV series was divided into 34 episodes in Japan, and the DVDs in both Chinese and Japanese went on sale on 20 June 2012.

The TV series was a big hit in 2011. “Xiaosan” or “Little Third” (小三), “the other woman” in the story, has become a popular euphemism thanks to the show. Also, merchandise has sold well in Taiwan and abroad. The popular drama was nominated for a number of Golden Bell Awards (Taiwan’s Emmys). Some controversial parts of the story received heated discussion, and the producer Wang Peihua (王珮華) decided to make it into a feature movie set four years after the main female character Xie Anzhen (謝安真) get divorced. A press conference to announce the film adaptation The Fierce Wife: The Final Episode (犀利人妻最終回：幸福男‧不難), was held on 20 January 2012. The film was released on 17 August 2012.
