After two days of Mercedes-Benz, the team finally arrived at the Gangtuo Bridge in Jiangda County, Changdu, Tibet, on the morning of October 12. This bridge is only 159 meters long and about 7 meters wide. It is the boundary bridge between Sichuan and Tibet. It has been open to traffic since December 1974 and crosses this bridge. It officially entered the territory of the Tibet Autonomous Region. Still nostalgic for the beautiful scenery on National Highway 317, here I received a warm welcome and warm reception from the local government leaders and the people: a bright smiley face, a white Hada, a sincere blessing, and prepared fruits and potatoes, washed away the dust all the way, The meaning of travel is not just in the scenery, but also in the different people you meet. In addition, Jiangda is still a memorable revolutionary place, the Jinshajiang 18th Army Ferry was here, after decades of wind and rain, still relatively complete retaining the historical scene and the achievements of the ancestors, Jiangda is also the first stop to liberate Tibet. Here you can also feel the intangible cultural heritage with local characteristics, Polo woodcuts and rock-than-crafts, etc., which is an eye-opener.
