The three international databases SCI, EI and CPCI are basically English-speaking countries. Like China's CNKI, they are all periodicals, papers, yearbooks and other data, but most of them are English periodicals, which have international influence. Of course, there should also be Chinese periodicals in it. Both foreign papers and domestic papers are papers, with the same content requirements and writing purposes, but with different languages and different format requirements. You should know that these things, including research routines, are all imported from the west, and the routines are basically the same. You ask this question because you don't know what a paper is. I suggest you find out what a paper is and what it is for. Learn to write a China paper first, and you will naturally know the problem.
