People may differ from each other in their interpretation of love. For Cao Yuehua and Wang Deyi, love means a happily married life that has lasted for 70 years.

Yesterday, Cao Yuehua, 97, and his wife Wang Deyi, 98, went back to the Beiwenquan scenic area where they had their first wedding photo photographed in 1945 and took another wedding photo, celebrating their platinum wedding anniversary.

"My darling, please give me a definite answer, which will reflect my once-pale youthful-ness……,” Cao Yuehua read the love letter he sent to his wife 70 years ago in front of the Shufan building in the Beiwenquan scenic area.

Cao Yuehua recalled that he wrote the letter in the trenches the night he arrived in Myitkyina after taking a military aircraft. Cao, a translator, was ordered to go to the battlefield in Myanmar in late July 1944. 

Cao returned China in triumph in late August 1945 and their engagement announcement was published on the Yunnan Daily on Oct. 20, 1945. More than 10 days later, they went to Chongqing and held a grand wedding ceremony in Shufan building in Beiquan scenic area.

Wang was struck by a cerebral infarction last year and from then on she cannot think clearly like before and even makes mistakes when she is asked how old she is. But she can still remember the details of their 70 years of love.

Cao Pangpei, youngest son of this old couple, said that his father, a student of Fudan University has a good command of English, Russian and French and his mother had studied in five universities in a succession.

With votes from more than 10,000 readers, Cao Yuehua and Wang Deyi crowned the World's Love Hero List 2013, an activity organized by the Chinese media.
