HAIKOU-- About four-fifths of the more than 54,000 living Chinese centenarians are women, and a 127-year-old woman from Northwest China is the oldest of them all, according to figures released on Wednesday.

The Geriatric Society of China (GSC) claimed the oldest person in China is Alimihan Seyiti, a Uygur who was born on June 25, 1886. She lives in Shule County in Xinjiang Uygur autonomous region.

If verified, Seyiti could be the oldest person in the world, beating by five years the Guinness World Record of 122 set by Jeanne Calment from France. Seyiti was honored by the GSC in June as the oldest person in China after the death of Luo Meizhen in Guangxi Zhuang autonomous region, who was born in 1885.

Xinjiang, Hunan, Yunnan, Shandong, Guangxi and Sichuan are home to China's 10 oldest supercentenarians (those who have attained the age of at least 110), and their average age is 119.2 years.

According to GSC figures, rural centenarians outnumber their urban counterparts. Among the 54,166 Chinese centenarians, about three-quarters, or more than 74 percent, are from the countryside.

The GSC also published a list of the 10 oldest couples in China, who are now living in the provinces of Hainan, Henan, Liaoning, Fujian and Shanghai Municipality.

According to the GSC, the oldest living couple are Ping Muhu and his wife Zhang Xinniu from Yuzhou city in Central China's Henan province, whose combined age stands at 213 years. The average combined age of the 10 oldest couples in China is 207.7 years.
