During a television interview, Su said she told Lo before their wedding that she "didn't want a celebrity, but a cook and an honest husband".
After they tied the knot in Beijing in December last year, Lo, who had never cooked before in his 47 years of life, picked up cooking just for his new missus.
According to Su, Lo called his mom in Hong Kong to get recipes and cooking tips.
"He took down notes about what ingredients go in first and what ingredient follows. Now he can cook a whole table full of delicious dishes!" she gushed.
Su went on to reveal that Lo not only took care of the meals but also handled other chores, from doing the laundry to watering the flowers in the garden.
The 34-year-old actress added that Lo took frequent breaks from filming to spend time with her. He loving husband also sends her daily phone messages and calls to tell her his whereabouts.
Interestingly, while Lo appears to be the perfect husband now, he was reportedly extremely nervous during his marriage ceremony with Su.
According to the event's master of ceremony Wang Dong, Lo was puffing away like a chimney just before the ceremony.
"There was a large pile of cigarette butts in the ash tray in front of him (Lo), which was so full it could not contain any more. But Lo kept stuffing more cigarette butts into it," said Wang.
Lo later explained that he didn't have a case of nerves due to the pressures of marriage, but smoked because he was exhausted from all the marriage preparations.
Lo's marriage to Su is his second. He divorced his wife of 10 years Clare Fong in 2008. The couple have an 11-year-old son.
Su and Lo met in China while working on television series "Perfect Ending". They dated for a year before getting engaged in January 2009.
