Work with Wikipedia

AFTER I known that we will work on Wikipedia, I thought it was easy. However, I know that I was wrong. So I started work with learn more.I learnt how to place an inline citation using ref tags from learn how page. I want add some footnotes for this article. How to create a footnote? I learnt that I have to use <ref>…</ref>syntax at the appropriate place in the article text which means I have to add this syntax before and at the end of the sentence. I also learnt several rules for adding the citation, such as text-source integrity, particularly contentious. From learn how, as well as I learnt how to create the list of citations. I will use "reflist"

when I want to add a list of citations. So I want to try what I learned in the article "the relationship between China and Philippines. I searched some sentences in google from this article, and then I found several articles talk about the China relations with Philippine.And some of this article are reliable source I think. It is because some of these article comes from official websites, such as ASEAN-China Centre, Philippine consulate general shanghai. I think some of these source can be add as citations. Then I learnt that what kinds of sources can be use as secondary sources. Now I am very clear about how to identifying reliable source."The source included the work itself(like a document, article, paper, or book) the creator of the work (for example, the writer), and the publisher of the work (for example, Oxford University Press). All three can affect reliability." Therefore, I can based on these three rules to judge the article which is reliable or not.
