Mr Eng previously worked as a manager for an international bank in his home country, and is now employed at a regional distribution centre - but lost more than £3,000 in earnings while off sick.
Lin has no previous convictions.
Donal Maguire, defending, said that the wound had been caused by her "pushing him away while holding the knife".
He added: "Can I deeply apologise on behalf of the defendant, publicly, to him? She expresses that she is deeply sorry for the consequences of her actions, both the injuries he sustained and the inconvenience he has clearly been put through.
"This was a stressful, anxious moment in the family home. In the background were fireworks, which it seems added to the stress of the incident.
"Her regret was immediate - she attempted to assist him as best as she could and expressed her sorrow there and then. Ultimately, her desire is to return in some form to the role she was fulfilling before this awful incident - being the mother to her child."
Lin admitted wounding and was handed a 12-month imprisonment suspended for a year.
She was also told to complete a rehabilitation activity requirement of up to 20 days.
The mother, wearing a pink raincoat in the dock, wiped away tears with a tissue as she was spared jail.
Sentencing, Judge Stuart Driver said: "A highly dangerous weapon featured, but it was a spontaneous and short-lived assault.
"You acted in the head of the moment due to the stress you had been under, and it was out of character. If I see you again, it is likely you will go straight to prison."
