The house was erected with hand-made tiles and bricks. And since they frequently had to climb up and down the mountain, Liu started hand-carving steps into the rocky ridges.
In 2006, the couple left their mountain retreat for the first time and an interview with China Central Television, after winning the award for China's greatest love story of the year.
In the interview, Xu recalled their harsh life in the first few years and said she often asked her husband if she was a burden.
"As long as we work hard enough, life will get better," Liu always answered.
In 2007, Liu passed away and Xu moved in with her sons, grieved and eventually died on Oct 30, this year. Her children buried her with Liu, according to Xu's wishes.
