They were apart for four years, meeting only once a year when Yuan took a business trip to Beijing. "We held the same picture, looked at the starry sky and thought of each other," Li says.

Four years later, Li applied to work in Baotou and not long after that, Yuan gave birth to two sons.

"We were apart for four years, so we cherished the days together and never wasted time in blaming each other. Life wasn't romantic or colorful at that time but it was like a cup of tea with a taste that lingers in your mouth for the whole day, and you don't want to miss it every day," Li says.

The family moved to Ningbo, Zhejiang province, in the early 1990s. The older son moved to the United States and the younger boy started his own business in Ningbo.

In 2005, their peaceful life was shattered when Yuan suffered a serious illness after taking the wrong medication. "She lost her memory and couldn't recognize anyone but me," Li says.

That was a difficult time for Li. He locked Yuan in the bedroom to prevent her from sneaking away and getting lost. On one freezing night she managed to leave the house, Li got out of bed and dashed out into the street bare-footed to look for his wife.

Miraculously, Yuan recovered fully five years later and they embarked on a blissful life in their twilight years. Li prepares breakfast for his wife every morning and wakes her up. He always calls her "my lover", a term usually avoided by the Chinese elderly.

Earlier this year, Li collected the pictures and memories of their life journey spanning nearly 80 years and made them into a PowerPoint slideshow. He collected his wife's pictures throughout her stages of life from a little infant in her mother's arms.

He can look at discolored and smudged black-and-white group pictures that were taken when Yuan graduated junior and senior high school, and point out his wife in an instant.

Li says the only time they argue with each other is when she complains about his cooking skills.

"We've felt a close affinity to each other through our lives and now hope to share the rest of our lives healthily and happily together," Yuan says.

"I'm lucky to have met the person destined for me in the palm of my hand," she says.
