The Nujiang River valley is one of the regions which have the worst environment and living conditions. Including many ways like history and society, the social development of different nationalities in the region is very slow. Until at the beginning of the Liberation, the Nus' society still stayed at the level of the end of primitive society, and the level of productive forces was low. People in most of the region still used wooden pickaxe and wooden stick, and slash-and-burn was main method of cultivation. Gathering and hunting were main sources for living. They didn't have enough clothes to cover their body and enough food in their belly.

After the establishment of the new China, the Communist Party and the government adopted a series of policies and measures, and helped the Nus, Drungs and Lisus in many aspects, such as politics, economy, culture and transportation. Now the old Nujiang River is still flowing with great waves and sound, but scenes on the sides of the river have had an enormous change. Changes of the Nujiang River can be vividly represented by the developing transportation facilities like bridges and road.

Nujiang was peacefully liberated in 1949. Before that year, there were only 500 kilometers of post road in the mountains in Nujiang, and they were always destroyed by mountain torrents because the road was very narrow. Two persons couldn't walk abreast on some country road, and two horses couldn't make way for each other. People climbed rattan, swung or walked on the single-plank high bridges. The transportation was very primitive and backward. After the setting up of the new China, transportation conditions have changed with each passing day and have got quick development. During the ten years from 1951-1961, post road of Nujiang had increased to 2000 kilometers. 

At the same time, transporting stations were set up, packhorses were increased, and animal-drawn carts were used. In 1956, the first road was constructed in Nujiang, and from then on, cars went into the region. Until 1984, there were 58 roads and traffic mileage was 883.5 kilometers. Besides, a single-arched crossing bridge, 5 road suspension bridges, 26 temporary bridges, 23 suspension bridges for humans and horses, 48 steel overhead cables, and other 188 permanent bridges have been built by the government over Nujiang River, Lancangjiang River, and Drung River. The length of post road has been increased to 6389 kilometers. The natural moat of the Nujiang River today becomes a thoroughfare, road extends in all directions and vehicles are unblocked. 

The Nujiang River is changing, and the tomorrow of the Nujiang will be better.
