A woman who abused and beat her lover's "slave" wife to death and the husband who let it happen have both lost appeals against their sentences.
The terms passed on Su Hua Liu, 29, and takeaway boss Lun Xi Tan, 42, were "richly deserved", said Lord Justice Laws at London's Court of Appeal.
Liu was jailed for nine years in May after admitting the manslaughter of Shaowei He, 25, in Rotherham in March.
Tan was jailed for six years for causing or allowing her death.
Dismissing the pairs' appeals as lacking "any scintilla of merit", the judge added: "Neither of them received a day too long".
Liu pleaded guilty to manslaughter and causing grievous bodily harm with intent at Sheffield Crown Court.
She had admitted killing Shaowei He, who was found dead in the garden outside the takeaway in Kilnhurst Road, Rawmarsh, Rotherham, on 23 March.
Shaowei He had died from haemorrhaging and shock due to multiple injuries and from hypothermia from being left outside all night in temperatures of minus four degrees centigrade.
The court heard the weapons used against her included a wok, a ladle, a broom, a copper pipe and a piece of wood which had seven nails driven into it for food orders to be hung upon.
Lord Justice Laws, sitting with Mr Justice Penry-Davey and Judge Elgan Edwards, the Recorder of Chester, said that it was an "horrific" story which "must turn the stomach of any humane person".
Tan, who already had a wife and family in Sheffield, married Shaowei He in China and brought her back to the UK in 2005.
The court heard she was working at Tan's shop as an "unpaid slave" for two years to clear the £20,000 debt which Tan said she owed him for coming from China.
Failed asylum seeker Liu, whose five-year-old son lives in China with her mother, met Tan through a lonely hearts advert and was installed at the shop as his mistress in August 2005.
Liu began assaulting Shaowei, who was of low intelligence and suffering from depression, when Liu became pregnant in February this year.
The judges heard that Liu, who was present for the appeal, had given birth to Tan's daughter last month.
The baby, who is in the care of social services as Wakefield's New Hall Prison has no mother and baby unit, is likely to be adopted and Liu deported on her release.
