cam duc » cao duc, pham duc, nam duoc
tai cua » thai cua, tai cuc, tri cua
han tai » hang tai, nhan tai, van tai
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu va » lieu va, hieu qua
va han » va phan, van han, va hanh
te cac » tu cac, ve cac, te cao
tu can » tu ban, tu cac, thu canh

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te cac) or (tu can)) ky tang xa hoi. hieu va ((cam duc) OR (cam xuc)) va han tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (tu can)) ky tang xa hoi. hieu va ((cam duc) OR (cam xuc)) va han tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) or (tu can)) ky tang xa hoi. hieu va ((cam duc) OR (cam xuc)) va han tai cua tre*".
