Abstract: The “two roads” spirit was a spiritual force that general secretary XI Jinping has condensed and emphasized many times， and it was also the spiritual symbol of national unity and unified efforts to build new China and the concentrated manifestation of the sense of community of the Chinese nation. The “two roads”spirit was formed in the transition period of the Communist Party of China from revolution to construction. It was a spiritual lineage category emerging in the field of transportation construction in new China， which takes the unity and common prosperity of the Tibetan and Han nationality as the core. In the new era， further study of the “two roads”spirit from the perspective of “forging the sense of community of the Chinese nation” will help expand the research horizon and interpretation space of the spiritual pedigree of Chinese Communists， and help grasp the main line of the party’s ethnic work in the new era to promote the construction of the common spiritual home of the Chinese nation.

Key words: Communist Party of China, “two roads” spirit, Chinese nation, community, spiritual home
