What is the difference between so do i and so do I?

As an English major teacher, I often use two similar and confusing expressions, So do i and So do. There are differences in meaning and usage between them, mainly as follows:

I'm English, too? Du? Answer? ] ? Beauty [so? Du? Answer? ] ? I am the same; Me too; I like it too.

So I do English? Answer? Du? ] ? Beauty [so? Answer? Du? ] ? I know.

Similarity: Both can be used to mean "Me too".

Difference: So? Do I focuses on what I said before, and it also applies later; So I pay attention to the latter and agree with the former.

Two: the difference in usage

So do I is mainly used to show that the above-mentioned situation also applies to the people or things behind, meaning "... so it is." The auxiliary verb do in this structure can also be changed into is, am, are, was, was, does, did, can, could, etc.

So I do is mainly used to strengthen the tone, indicating that "it is true, it is true, indicating that the latter agrees with the former's words or views, but further emphasizes and repeats the contents mentioned in the previous sentence. The subjects of the preceding and following sentences refer to the same person or thing. The auxiliary verb do in this structure can also be changed into is, am, are, was, was, does, did, can, could, etc. According to the previous situation.
