Welcome
Hello, and welcome to Wikipedia! Thank you for your contributions; however, please remember the essential rule of respecting copyrights. Edits to Wikipedia, such as your edit to the page H. K. Yang, may not contain material from copyrighted sources unless used with permission. It is almost never okay to copy extensive text out of a book or website and paste it into a Wikipedia article with little or no alteration, though you can clearly and briefly quote copyrighted text in the right circumstances. Content that does not comply with this legal rule must be removed. For more information on this, see:
 * Copy-paste
 * Policy on copyright
 * Frequently asked questions on Wikipedia's copyright policy
 * Policy and guideline on non-free content

If you still have questions, there is a new contributor's help page, or you can write   below this message along with a question and someone will be along to answer it shortly. You may also find the following pages useful for a general introduction to Wikipedia:
