There is no consensus of classification of cities except for the big 4 in tier one.
But some cities measured in this survey are not normally regarded as tier 2 cities, for example some capitals of Southwestern provinces, such as Kunming and Guiyang (some people think they are "lower tier 2")
I can show you some cities of tier 3/4 according to the criteria of

I'll choose citer/3/4 cities not in Coastal China to show the development of the interior.
Because even a non-tier county town in Coastal China will look like a super city.

Pls refer to #39.
There are significant differences of definition of cities between in China and abroad.
(A city in China= a real city + several counties)
We usually do not talk about the tiers of a county and the main towns of a county.
But these county townships are de facto small cities, can be classified as tier 4/5 or no tier if too small.
(A county=the main county town+ several more rural towns/townships)
Zunyi County, Guizhou Province, Southwest China
You can see the rural townships at the beginning and the main county town at the end
