In 1998, Professor Humes and Doctor Ryals traveled with Edward Nixon, the brother of the President, to the People's Republic of China. While retracing Nixon's steps, they interviewed those Chinese Foreign Service experts who had planned the president's meetings with Mao Tse-tung and Chou En-lai. These protZgZs of Chou En-lai ended their diplomatic careers as envoys in Anglophone nations such as the U.S., U.K., Canada, and Australia. During interviews with Humes, Ryals, and Edward Nixon, these experts shared their observations about the forces, such as the Gang of Four, who were plotting to prevent the Nixon Trip, as well as why, at the time, Mao was amendable to restoring ties with America despite the ongoing Cultural Revolution.
