Source #6

1.) http://en.wikipedia.org/wiki/Chinese_painting
2.) The source of this is wikipedia.
3.) Doesn't provide any credentials or an individual person for the site.
4.) They provide a lot of information on Chinese painting, the history of it and where it originated from like which dynasties.
5.) I believe this source.
6.) Because they give a lot of information on Chinese painting, which is a lot like the information I have found on other sites, so it's pretty believable.
