There is nothing free on the paper net. It is better to write it yourself than to spend RMB. Not if you cheat. If the writing requirements are not high, there is a simple method. First, you probably determine your topic, and then look up a few similar articles on the Internet and read them through to get a general understanding of this. Referring to the format of the paper, you should list the outline and supplement the content. It is really no good to synthesize these papers, copy a part from each paper, form a new article, and then replace each part with a sentence or word according to your own language.

Can't write to help you.
