Peng wrote a long letter to Mao telling him what was wrong with the execution of the Great Leap Forward. Can anyone point to that document online, in either Chinese or English?

Mao also wrote poems and newspaper articles on the subject.

Any pointer would be greatly appreciated. I am researching for a book a Chinese friend is writing.
