2013 film by Feng Xiaogang

The odd-couple courtship saga continues of wealthy, middle-aged retiree Qin Fen and serious-minded young air hostess Xiaoxiao. After an amusing prelude in which Qin presides over a lavish divorce ceremony for an amicably splitting married couple, he and Xiaoxiao decide to address their own relationship barriers — her youth and beauty, his cynical, childish sense of humor — by entering into a trial marriage while on a trip to the country's tropical southeast.

Qin Fen, a funny, honest, single inventor, met a girl called Smiley, who was in agony of her boyfriend's betrayal. They traveled to Hokkaido, tried to help Smiley cure her pain in heart, and both of them gradually found their true love and life redemption during the journey.
