If you voted in English before, it is ok for domestic publications to vote in Chinese, because it is impossible to copy one Chinese and one English, but you can't vote in Chinese completely mechanically. You need to modify the title, abstract and conclusion appropriately, and then redraw the picture of the article and modify the data in the table appropriately, so there is basically no problem. Of course, if you still don't understand why you can do this, I suggest you search Baidu: EI Academic Conference Center, which contains a lot of information about EI conferences and analyzes the process of "one China, one English" in detail.
