Which city is better, Mianyang or Guiyang?

Compared with Guiyang, Mianyang is a better city. It has its own history and has existed in China for 2000 years. And some of its own climate is very mild, which is very suitable for tourists to travel. Some of its famous scenic spots are also welcomed by the public, and Mianyang is also a science and technology field established by a country with strong scientific and technological capabilities. It has brought a different shock to the country and trained a generation of scientific and technological talents, so I think Mianyang is a very advanced city.
