Almost a fifth of couples in some of Hong Kong's strongly working-class districts would be more prepared to tolerate their partners' extramarital affairs than split their family up in these financially uncertain times, a poll found. The poll of 1,416 adults in the western New Territories - with working-class districts such as Tsuen Wan and Kwai Tsing - found their desire to keep their family together had grown stronger since the global financial crisis hit and they would be more likely to excuse a cheating spouse. The Caritas survey was conducted between July and August. Caritas social work supervisor Lam Keung said it was concerned about the high tolerance level to infidelity. 'Most of the respondents think they do not want to have a broken home at this time,' he said. As well as infidelity, the poll found 16 per cent would excuse a gambling addiction to keep their family together, while 10 per cent said they would tolerate violence being used against them for the sake of their children. Two couples, though, both married for more than 30 years, said their decision not to leave their partners despite extreme problems had left them in a better position today. Chan Kwong-woon, 63, and his 56-year-old wife, Lo Kwan-hing, have been married for 39 years. Chan lost his legs when he fell and was hit by an MTR train about 11 years ago, but despite their financial disadvantage, the couple supported each other and their three sons. 'I was hopeless when I lost my legs. Luckily, my wife stayed with me and took care of me. We do not quarrel. We love each other,' Chan said. Former gambling addict Kwan Ping-wah, 57, said his wife tried to commit suicide many times because of it. His wife, Yan Lai-yung, 50, said she even contemplated killing her five-year-old son by pushing him out of a window nearly 16 years ago. Kwan's gambling addiction lasted 40 years. 'I was the troublemaker in the family, but I really thank my wife for not leaving me. I'm grateful to have her in my life.'
