However, you must follow the licensing terms which govern all Wikipedia text. Most of Wikipedia's content, including the text you are using, is dually licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC-BY-SA 3.0) and the GNU Free Documentation License (GFDL) (unversioned, with no invariant sections, front-cover texts, or back-cover texts). The text of these licenses, the relevant legally binding documents, can be found at <https://www.duhoctrungquoc.vn/wiki/en/WP:CCBYSA> and <https://www.duhoctrungquoc.vn/wiki/en/Wiki:Text_of_the_GNU_Free_Documentation_License>. Wikipedia does offer advice about how to comply with these licenses. This can be found in detail at <https://www.duhoctrungquoc.vn/wiki/en/Wiki:Copyrights>.
First, I would like to point out that when you use content from Wikipedia you should include a link back to the source Wikipedia article as is suggested at that page. Additionally, you should also include a CC-BY-SA notice, a GFDL notice, or both. You could, for example, add the text "This article is licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License, which means that you can copy and modify it as long as the entire work (including additions) remains under this license", and provide a link to a copy of the CC-BY-SA. Text such as "This page contains text from Wikipedia, the Free Encyclopedia" is a good way to acknowledge the general source of the text.
Specifically, your page

Dear (RECIPIENT'S NAME),
I am delighted to see that your service provider, (ISP NAME), hosts a website, (SITE NAME) at
However, (SITE NAME) does not currently comply fully with the terms of either license. For instance, the duplicated content must link to one or both of the CC-BY-SA license and the GFDL, and must attribute its original source. As a result, (SITE NAME) includes unauthorized duplicates of Wikipedia content. Moreover, I have been unable to reach the site maintainers. Multiple requests have been sent to (SITE EMAIL) regarding this oversight without response; the last such request is appended below.
As you are the Designated Agent for (ISP NAME), I am sending you this formal takedown request as a last resort. The following articles, among others (including most of the content duplicated from Wikipedia), are being made available for copying through downloading from the listed URLs, without authorization from the copyright owners.
I personally hold copyright in the following articles:
1. (ARTICLE NAME) Original:Infringing copy: Date found: (DATE) 2. (List others in same format)
I am giving notice of these activities pursuant to Section 512 of Title 17 of the U.S. Code (https://www.copyright.gov/title17/92chap5.html#512). The information in this notice is accurate; I have a good faith belief that this use of the material is not authorized by me, any agent of mine, or the law. I swear under penalty of perjury that I am the copyright holder of the above works. Please act quickly to remove the materials described above until they comply with this law and the CC-BY-SA.
Please advise regarding what actions you take.
Yours sincerely,
(SENDER'S NAME)
