No Regrets (Chinese: 巾幗梟雄之義海豪情) is a 2010 Hong Kong period television drama created and produced by Lee Tim-shing for TVB as a grand production.

Most of the original main cast signed on to film the sequel, with the exception of Kiki Sheung, Ron Ng, and Suki Chui, who were reported to be not taking part in the production due to schedule conflicts.

"[4] Sheren Tang and many of the other cast members also agreed and expressed that the ending to Rosy Business was perfect, and that there was no need to film a direct sequel but could rather do a whole new story.

[5] It was announced that the sequel will be a completely different story taking place during World War II in Guangzhou, about 100 years after the events of Rosy Business.

Holding a deep hatred for drugs, Miss Kau hopes to gain full control of her father's expansive opium business in order to destroy it from within.

"[12] Tang describes Miss Kau and Sing's romantic relationship as "extremely complicated; there's love and hate, right and wrong; and most of the time, they oppose each other.

[14][15] Sheren Tang returned to Hong Kong from filming New My Fair Princess for most of the events including TVB's Lighting Ceremony to promote the drama as an anniversary series with the rest of the cast.

Several cast members including Tang, Lai, and Ngo also did multiple interviews on TVB's afternoon talk show, The Green Room.

In 2011, Tang and Lai also did interviews and held concert events internationally at Casino Rama in Toronto and Genting in Kuala Lumpur in June and November respectively.

[16][17] In September, the two were seen in Taiwan promoting the series at Shilin Night Market[18] and on a TVBS cooking program, in addition to attending the Shanghai premiere event.

This choice along with Sheren Tang and Wayne Lai's onscreen chemistry were highly praised as the undying and unspoken love between the main leads, Cheng Kau-Mui and Lau Sing, felt much stronger than a typical romance and was very well received while some believed there could have been more romantic elements.

One of the series’ few criticisms was Chen's character's death and funeral, as it was deemed too long taking up the first half of episode 31, which aired as part of the finale.

No Regrets, however, featured additional themes including war, rivalry, righteousness, love for one's country and history which has not been seen before in Hong Kong dramas.

Mak Cheung-ching was also given credit for playing such a hated character so convincingly that his catch-phrase "My name Leung Fei Fan will be written backwards!"

[26] However, viewers found that the props and set used were incorrect and unconvincing for the 1930s and 1940s and did not bring out the chaotic times of that era, largely due to the lack of budget.

After winning the Best Actor and Best Actress awards for Rosy Business, Wayne Lai and Sheren Tang successfully defended their titles based on their brilliant performance in this drama respectively.

Complaints were lodged immediately after the ceremony ended to TVB directly and online, with many saying that No Regrets should have won because of its high ratings as well as critical acclaim and better plot.

Several shops and restaurants in Hong Kong were spotted closing early, posting signs citing returning home to watch the finale as its reason.

[1] This decision was originally in part due to Gun Metal Grey, the other anniversary series airing at 9:30, being deemed too violent and mature for the earlier time slot.

Plans were resumed, with the new female leading role being played by Myolie Wu because Sheren Tang was unavailable due to scheduling conflicts in addition to her contract at an end with TVB in 2012.

Audiences were disappointed with the poor plot, one-dimensional characters, and unnecessary, overused sexual violence, with fans disregarding the series as part of the franchise.

[20][36] News of a fourth sequel began in November 2020 with sources stating that filming will begin in March 2021 with Lai and Tang set to return with new cast members Rebecca Zhu, Gabriel Harrison, and Pinky Cheung.

New creator, Dave Fong Chun Chiu, who previously directed episodes for Rosy Business and No Regrets, said that the project is in the works but nothing had been confirmed.

[41] Despite massive excitement and enthusiasm from audiences and returning fans, on 19 July 2021, news outlets reported that collaborations with Chinese streaming platform Youku had fallen apart when the company exited the project after reading the first 3 episodes of the script.

[42][43] In late August 2021, it was reported the project will go ahead with filming set to start in March 2022 after investment problems were solved, but Zhu may no longer be involved.

[45][46] However, on 18 October 2021, Tang hosted a 90-minute live broadcast with Lai on Weibo in celebration of No Regrets' 11th anniversary where she openly addressed Rosy Business 4 for the first time.

She confirmed through a lengthy post on social media explaining her decision, which was largely in part due to a past unhappy filming experience and the multiple delays and cancellations of the project.

With Wayne Lai portraying the righteous police officer Lau Sing and Sheren Tang portraying Cheng Kau Mui (Miss Kau), a good-willed daughter of a triad boss holding a facade as a drug lord to save people, No Regrets includes some of the biggest issues and historical events during the time when the drama is set.

After the defeat of the Japanese Imperial Army in 1945, the country faces an economic crisis before civil war ensues, which, as portrayed at the latter part of the drama, affects the triads and directly affects Miss Kau; she held a facade as a ruthless opium dealer and a woman who cooperated with the Japanese Imperial Army for an opium business, when the new government of the Chinese Communist Party takes control, establishing the People's Republic of China in 1949.

The drama concludes with Miss Kau and Lau Sing reuniting in 1979 in Canton, and living life together in the early 1980s in Hong Kong and travelling around the world.
