When changing artists in batches, can I add text before , such as Qiansheng Music , but if I add it like this, it will overwrite the original, which is not what I want

If you use the tag panel then you can input only real characters but no variables.  
The `<keep>` refers to "keep all the data that is already there as is". Any modification would adopt only that. (Which is more or less what you found out).

To append a string to a field, see the FAQs on [How to append a string to a field](https://community.mp3tag.de/t/actions-and-batch-operations/967/5)

Select the files that should get the same string appended.  
Select the function Converter\>tag-Tag  
(as an example) Select the field ARTIST  
Enter as  
Format string: %artist% my appended text  
Click OK  
This adds the text "my appended text" to the already present data in the field ARTIST
