van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
tai cua » thai cua, tai cuc, tri cua
nang co » nang cao, nang doc, nang noi
xuc van » duc van, luc van, vuc van
tu bat » tu ban, tu dat
co lai » con lai, o lai, co dai
tu san » thu san, tu ban, tu can
ve cac » vien cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu bat) or (tu san)) ky nang co lai. hieu ((ve cac) OR (va cac)) xuc van hanh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu bat) OR (tu san)) ky nang co lai. hieu ((ve cac) OR (va cac)) xuc van hanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bat) or (tu san)) ky nang co lai. hieu ((ve cac) OR (va cac)) xuc van hanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu bat) or (tu san)) ky nang co lai. hieu ((ve cac) OR (va cac)) xuc van hanh tai cua tre*.
