Chinese athlete Liu Xiang，winner of gold medal in the men's 110m hurdles at the Althens Olympics，published his book，I'm Liu Xiang，recently in his hometown of Shanghai．

It seems that many people can't help comparing Liu Xiang with another Shanghai native，basketball giant（巨星）Yao Ming，who also recently published his book，A Life in Two Worlds．Manager Dai，the editor of the book I'm Liu Xiang，explained the differences between the two books as he saw them．Firstly，Yao's book was written mainly for Americans，while Liu's readers will be mainly Chinese．Secondly，A Life in Two Worlds was written in the third person singular（单数）by an American writer who recorded Yao Ming's stories．I'm Liu Xiang was written in the first person and included many articles from his diaries．Lastly，according to Dai，Yao enjoyed the advantage of being born in a sporty，rich family，unlike Liu，who came from a working class family and therefore had to go through greater hardship（艰难）before becoming a world-known athlete．So if you enjoy reading about mental（精神上的）suffering and physical pain，read I'm Liu Xiang．If you want to practice your English，read A life in Two Worlds．
