I used Post-It stickers on every document and wrote the chinese description
for my parents. They can take the stickers off. I also used the Post-It
Page Markers http://www.officedepot.com/a/products/444983/Post-it-Page-Markers-1-2/ on the side of each document and wrote the document # on it. Also prepare a list of documents with #s so it's very easy to find the one you need.
