Rosy Business (Chinese: 巾幗梟雄; Jyutping: gan1 gwok3 hiu1 hung4) is a 2009 Hong Kong period television drama produced by Lee Tim-sing and TVB.

After falling ill, patriarch Chiang Kiu temporarily hands over his leadership to his fourth wife Hong Po-kei, which incurs conflict with his other wives and sons.

Meanwhile the impoverished coolie Chai Kau becomes an important figure in assisting Hong Po-kei in protecting the family business from crumbling during the Taiping Rebellion.

A few days after the disaster, an official from Beijing arrives to the city to check the military supply, and upon seeing empty trailers, he sentences the Hong family to death.

Twenty years later, Po-kei reunites with the rich rice merchant Chiang Kiu (Elliot Ngok) at his manor in Wuxi, whom she was betrothed to before the disaster.

Chiang Kiu's wife, Yan Fung-yee (Susan Tse) recognizes Po-kei and reveals her identity to Prince Wai, who was there for a visit.

Appreciating Po-kei's wisdom and persistence, he entrusts the business to her, with the reason that his eldest son, Bit-man (Ngo Ka-nin), is not yet ready to succeed him.

She is impressed with second son Bit-ching's (Ron Ng) intelligence and guides him to become the successor, but her efforts are met with challenges from an employee, Chai Kau (Wayne Lai).

Hong Po Kei (Sheren Tang), one of Prince Wai’s (Kwok Fung) chefs, along with other servants are delivering a batch of rice to the city of Wuxi.

Along with producing coordinator Cheung Wah-biu, they submitted an initial script to Catherine Tsang, manager of TVB's production department.

A press conference and costume fitting for the cast was held on July 25, 2008 with the working title "Red Powder Merchant" (紅粉商人).

Lee explained that the production was temporarily called "Wives and Concubines" (妻妾成群) when the initial script was first submitted, but was later renamed to "Red Powder Merchant."

Additionally, the series swept all four MingPao Anniversary Awards: Best Actor for Lai, Best Actress for Tang, Best Programme, and Best Backstage Crew for writers Cheung Wah-biu and Chan Ching-yee.

Some viewers expressed that the story was similar to The Grand Mansion Gate, despite having a different plot, historical time period, and characters, and claimed that Hong Kong script writers were beginning to lack creativity, having remade a few Mainland dramas already in the past.

[31] After the success of Rosy Business, TVB announced plans to produce a companion piece starring the original cast, slated to begin filming in March 2010.
