Travelers heading down different paths do not plan together how to travel. Originally, the saying meant people with different views and beliefs do not seek to work together. Dao (道 way), which originally referred to “road,” is extended to include opinions, beliefs, interests, viewpoints, and guiding principles. Mou (谋 plan), is extended to mean cooperation and collaboration. In order to work together, it is most important to agree upon a set of common goals and principles. Without them, parties cannot collaborate successfully. On the other hand, collaboration should not sacrifice principles. Upholding principles does not mean rejecting cooperation. Rather, it means rejecting unprincipled deal-making. This is true of cooperation among individuals and among countries as well.
