va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, mang xa
van lam » van nam
lam xuc » cam xuc, lam duoc
nang ma » tang ma, sang ma, nang cao
xuc va » duc va, tuc va, luc va
vi cuu » vinh cuu
vi luu » vi lua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky ((nang xa) or (nang ma)) hoi. hieu van lam xuc va thanh ((vi cuu) OR (vi luu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((nang xa) OR (nang ma)) hoi. hieu van lam xuc va thanh ((vi cuu) OR (vi luu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((nang xa) or (nang ma)) hoi. hieu van lam xuc va thanh ((vi cuu) OR (vi luu)) tre*".
