Zhou Suhong (former Chinese women's NT player) and Tang Miao (former Chinese men's NT player) divorced.
But it's not a break-up. After Tang had an accident and became paralyzed in 2007, his wife, Zhou, has been taking care of him wholeheartedly. They made an appointment, if Tang could not fully recover in 5 years, they would divorce. Now they're still living together like a family, and they regard each other as brother and sister.
I don't think I've ever heard such a strange story...making a time-based plan for divorce depending on recovery...it sounds rather cruel.
