"Super Dan", as top-seeded Lin Dan of China is better known in the badminton（羽毛球） world, had his Olympic dream come true after claiming the men's singles gold by beating Lee Chong Wei of Malaysia on August 17 in the Beijing Olympics.

His father, Lin Jianbin, said "Super Dan"has waited for four years to get this championship and he felt very proud of his son, as well as his prospective daughter-in-law Xie Xingfang, who is also a badminton player and won silver in women's singles at the Beijing Games.

An SMS: The beginning of a love story

Lin was born in Shanghang County, Longyan in Fujian Province. He first met Xie Xingfang when he was 14-years-old. 16-year-old Xie was attending a national youth team badminton training camp in Jinjiang, Fujian and Lin was also there.

Tall and beautiful, Xie became the Snow White in the heart of Lin Dan, and he tried to please her and get chances to chat with her after the training sessions. He did not go beyond that.

Before the Spring Festival in 2004, Lin finally mustered（召集，聚集） the courage and sent Xie Xingfang a text message - I LOVE YOU. In fact, Xie Xingfang had already realized Lin Dan was fond of her. And covertly（秘密地） , she began to pay attention to Lin's movement and performance on the court. "He is very interesting, got a lot of ideas, and is a lovely boy."

Two Kisses

In May 2004 at the Thomas Cup in Jakarta, their love relationship was first known to the public. Xie sat with her teammates and watched the men's team playing. When Lin Dan won the match, he rushed to the bench and kissed Xie, a move that Xie did not expect Lin to do in public. A photographer captured this moment.

At the All England Open in 2007, Lin kissed her again in public, making Xie feel like the happiest woman in the world.

After Lin won his third title at the Open, he did not stay to watch Xie play. Xie defeated her opponent and won the championship. When she was called to accept the trophy（奖品，战利品） , Lin suddenly emerged at the central venue, holding red roses and gave her the flowers, and a passionate kiss.

Nine Roses

Earlier, on February 14, 2006, Lin and Xie were with the national badminton teams at a training camp in Jinjiang. The teams had their rules – not going out of the training camp. Xie thought she would spend the Valentine's Day without flowers.

But Lin still managed to give her a surprise – giving her a Dior wallet as a Valentine's gift and nine roses. With the teams' rule in place, Lin asked his local friend to buy the roses and gave her a pleasant Valentines surprise.

A 200-square-meter apartment

Lin Dan and Xie Xingfang's love has been through four years of tests, and Xie's father also said that they should consider marriage after the Olympics.

In fact, Lin Dan has already prepared for this. He has bought a 200-square-meter apartment in downtown Beijing, with 4 rooms and 2 living rooms. Paying about 20,000 yuan per square meter for the apartment, it is reported the apartment is now valued at 8 million yuan.

"After the Olympics, we really want to live our own lives, go on vacation, go to school, get married, I am really looking forward to it," Xie said happily.

With two kitchens, one Chinese and one Western style, Xie said she wanted to be the person preparing soup at home and enjoy family life.
