Which city in Northeast China is the most livable?

I have traveled all over the three northeastern provinces and eastern Inner Mongolia, and Dandong should be the first choice for living in the northeast. The main points are as follows: 1. The city is not near the river or the sea, with good environment, good air and beautiful scenery. Shenyang is several degrees higher than Benxi in winter and several degrees lower than Benxi in summer. Spring is not as windy as Dalian, and the tail vein of Changbai Mountain blocks the cold wind in late autumn and winter. 3. River fresh seafood, delicacies and whole grains are complete. 4. Convenient transportation The air high-speed rail expressway can go directly to Harbin, Changsha and Shenyang in the north. Dandong, the largest port city in China that I have been to, is the most beautiful.
