cam tuc » cam xuc, cam tu, nam thuc
va hanh » van hanh, va thanh, dao hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
te cac » tu cac, ve cac, te cao
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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 ky nang x hoi. hieu ve cam tuc ((((va hanh) or (ban hanh))) or (va danh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang x hoi. hieu ve cam tuc ((((va hanh) OR (ban hanh))) OR (va danh)) vi cua tre.
• Adding a wildcard symbol may retrieve word variants: te cac ky nang x hoi. hieu ve cam tuc ((((va hanh) or (ban hanh))) or (va danh)) vi cua tre*.
