Welcome!

Hello, Alexzhang101, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your edits have not conformed to Wikipedia's verifiability policy, and may be removed if they have not yet been. Wikipedia articles should refer only to facts and interpretations that have been stated in print or on reputable websites or other forms of media. Always remember to provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles. As well, all new biographies of living people must contain at least one reliable source.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Here are a few other good links for newcomers:
 * The five pillars of Wikipedia
 * How to edit a page
 * Help pages
 * Tutorial
 * How to write a great article
 * Simplified Manual of Style

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you have any questions, check out Where to ask a question, ask me on my talk page, or you can type   on your user page and someone will show up shortly to answer your questions. Again, welcome!

Hello Alexzhang101, and welcome to Wikipedia. Your addition to Plough has had to be removed, as it appears to have added copyrighted material without permission from the copyright holder. While we appreciate your contributing to Wikipedia, there are certain things you must keep in mind about using information from your sources to avoid copyright or plagiarism issues here.


 * 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 a cited source. You can read about this at Non-free content in the sections on "text". See also 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. (There is a college-level introduction to paraphrase, with examples, hosted by the Online Writing Lab of Purdue.) Even when using your own words, you are still, however, asked to cite your sources to verify information and to demonstrate that the content is not original research.
 * Our primary policy on using copyrighted content is Copyrights. You may also want to review Copy-paste.
 * In very rare cases (that is, for sources that are public domain or compatibly licensed), it may be possible to include greater portions of a source text. However, please seek help at the help desk before adding such content to the article. 99.9% of sources may not be added in this way, so it is necessary to seek confirmation first. If you do confirm that a source is public domain or compatibly licensed, you will still need to provide full attribution; see Plagiarism for the steps you need to follow.
 * Also note that Wikipedia articles may not be copied without attribution. If you want to copy from another Wikipedia project or article, you can, but please follow the steps in Copying within Wikipedia.

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. Dougweller (talk) 05:47, 29 September 2013 (UTC)
