Wikipedia and copyright
Hello 74.119.196.51! Your additions to Pan Jianwei have been removed in whole or in part, as they appear to have added copyrighted content without evidence that the source material is in the public domain or has been released by its owner or legal agent under a suitably-free and compatible copyright license. (To request such a release, see Requesting copyright permission.) While we appreciate your contributions to Wikipedia, there are certain things you must keep in mind about using information from sources to avoid copyright and plagiarism issues.


 * You can only copy/translate a small amount of a source, and you must mark what you take as a direct quotation with double quotation marks (") and cite the source using an inline citation. You can read about this at Non-free content in the sections on "text". See also Help:Referencing for beginners, for how to cite sources here.
 * Aside from limited quotation, you must put all information in your own words and structure, in proper paraphrase. Following the source's words too closely can create copyright problems, so it is not permitted here; see Close paraphrasing. Even when using your own words, you are still, however, asked to cite your sources to verify the information and to demonstrate that the content is not original research.
 * We have strict guidelines on the usage of copyrighted images. Fair use images must meet all ten of the non-free content criteria in order to be used in articles, or they will be deleted. To be used on Wikipedia, all other images must be made available under a free and open copyright license that allows commercial and derivative reuse.
 * If you own the copyright to the source you want to copy or are a legally designated agent, you may be able to license that text so that we can publish it here. Understand, though, that unlike many other sites, where a person can license their content for use there and retain non-free ownership, that is not possible at Wikipedia. Rather, the release of content must be irrevocable, to the world, into either the public domain (PD) or under a suitably-free and compatible copyright license. Such a release must be done in a verifiable manner, so that the authority of the person purporting to release the copyright is evidenced. See Donating copyrighted materials.
 * Also note that Wikipedia articles may not be copied or translated without attribution. If you want to copy or translate from another Wikipedia project or article, you must follow the copyright attribution steps described at Copying within Wikipedia. See also Help:Translation.

It's very important that contributors understand and follow these practices, as policy requires that people who persistently do not must be blocked from editing. If you have any questions about this, you are welcome to leave me a message on my talk page. Thank you. Moneytrees🏝️Talk/CCI guide 18:02, 29 November 2021 (UTC)

Hello. This is a message to let you know that one or more of your recent contributions, such as the edit you made to The Battle at Lake Changjin, did not appear to be constructive and have been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page.

Please refrain from making unconstructive edits to Wikipedia, as you did at Chengdu J-10. Your edits appear to be disruptive and have been or will be reverted. Please ensure you are familiar with Wikipedia's policies and guidelines, and please do not continue to make edits that appear disruptive. Continued disruptive editing may result in loss of editing privileges. Thank you. - RovingPersonalityConstruct (talk, contribs) 22:12, 29 December 2021 (UTC)
 * If you are engaged in an article content dispute with another editor, please discuss the matter with the editor at their talk page, or the article's talk page, and seek consensus with them. Alternatively, you can read Wikipedia's dispute resolution page, and ask for independent help at one of the relevant noticeboards.
 * If you are engaged in any other form of dispute that is not covered on the dispute resolution page, please seek assistance at Wikipedia's Administrators' noticeboard/Incidents.

User:Shulinjiang, your ability to assess and use sources remains terrible. First, worldpopulationreview.com should not have been used; it's a non-notable self-published source (WP:SELFPUB) and so should not be used. Second, as the site claims to just use data from other sources (see their about page) this should have led you to dig into the sources they claim to be using (there's a list at the bottom of each page.) If you had done this, you would have discovered that the source data is from 2019/2020. Third, you would have realized that something is wrong with worldpopulationreview.com because the sources it claims to be using do not necessarily match with the data it is displaying; the sources are not in agreement, and the UN data is for five-year intervals.

The bottom line is that you have - again, and in typical fashion - made poor edits due to a lack of conscientiousness and a poor understanding of core editing policies like WP:VERIFY. - RovingPersonalityConstruct (talk, contribs) 21:09, 5 May 2022 (UTC)
