There are two types of ordering methods, and we mainly use traditional ordering methods. Is this sentence correct?

I think this sentence has a speech defect, ''There are two kinds of ordering methods'', it lacks the subject, where are the two kinds of ordering methods? Does it refer to our country alone, or does it refer to the world? There are also improper collocation of statements, the use of traditional ordering methods should be changed to the use of traditional ordering methods , because the use of ...... ways, methods, this is a fixed collocation.

Thus, the sentence can be changed to: there are two kinds of ordering methods globally, and our country mainly adopts the traditional ordering method.

Or there are two ways of ordering in our country and we mainly use traditional ordering methods.
