The Hurun lists of the richest women on the Chinese mainland and the world's richest self-made women were released Wednesday.

Wu Yajun, 47, General Director of Longhu Real Estate Development Co, a developer in the southwestern municipality of Chongqing, tops both lists as the richest Chinese woman, with an estimated family fortune of 420 billion yuan ($6.6 billion),

The list is made up of the 50 richest women selected from China's Hurun Rich List 2011 which has 156 women in its 1,000 richest people in China, accounting for 15.5 percent of the list, reaching a record high.

The average age of the 50 richest Chinese women is 48, three years younger than the overall figure of the Hurun Rich List 2011. The average wealth of the listed women is 9.7 billion yuan, up 13 percent from last year, the highest level in history.

The real estate industry remains the biggest source of wealth for the 50 richest Chinese women, with 18 coming from this industry and six among the top 10.

Guangdong province is home to the headquarters of 10 listed women's companies, more than any other region in China, followed by Beijing with nine and Zhejiang with six.

Thirty-three of the 50 richest Chinese women are self-made billionaires, up from last year's 30.

On the list of the world richest self-made women, 18 who have more than $1 billion come from China.
