van dinh » van dich, xuan dinh, tran dinh
nang xa » nang x, lang xa, nang ma
nam xuc » cam xuc, nam xua, nam thuc
va dinh » va kinh, va tinh, vu dinh
cua tre » cua te, cuu tre, cua triet
tai ky » thai ky, trai ky, sai ky
ve cua » le cua, de cua, te cua

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

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