TWO Chinese brothers say they were trying to "save face" when they bashed a man with a hammer in his own home.
Kun Zhang, 28, and Jin Zhang, 27, believed Chang Bo Wang - who worked at a chicken factory with Kun's wife - was having an affair with her.
Brisbane District Court heard this was a source of great humiliation for Zhang and the concept of saving face was valued highly in the Chinese culture.
Crown prosecutor Shauna Rankin said Zhang had phoned Wang on September 22, 2010, to confront him about his suspicions.
She said Wang told him to go over there because he had swords and he would be waiting for him.
Zhang, his brother and three others went to the house the next morning about 6.45am with a hammer and metal bars.
Three of them went inside where they found Wang cooking breakfast.
One held him while the other two punched and hit him with the hammer, causing bruising to Wang's head, torso, hands and feet.
Wang, who had been cooking with a cleaver, regained control of the knife and chased them out of the Sunnybank Hills house.
Defence barrister Alastair McDougall said the internet was littered with information about the Chinese cultural concept of loosing face and the need to save reputation.
He said his client was married with two small children at the time.
His wife has since returned to China and Zhang has a 12-day-old son with a new Australian partner.
The court heard his brother was probably still drunk from the night before, was conscious of family shame and loyal to his father.
Judge Leanne Clare said both men now feared deportation because of their actions.
She said the man they hurt was an illegal immigrant who had gone into hiding.
Judge Clare described the offences as a "pre-meditated violent confrontation with a weapon in company upon a man in his own home".
She sentenced Kun to 14 months jail, suspended after he has served four months.
Jin must serve three months of a one-year jail term.
