Josh has pointed out that Wikipedia already has an article about this person - the article is at Peggy Yu.
So what would be best would be for you to add your information directly to that article.
Another suggestion, is to make sure that all the information you add, is neutral and based on reliable sources. So for example, if you say that someone is "easy going" or "knows how to enjoy life", make sure that you have a reliable source (reference) that says so.
Also, it is best not to include material unless it is really relevant to the information one would expect in an encyclopedia. So, to say that she enjoyed a birthday party, is not really needed.
