xa thanh » va thanh, ha thanh, ta thanh
nang tuc » nang thuc, nang luc, nang tu
cua tre » cuu tre, cua triet, dua tren
tu lanh » tu hanh, tu lenh, tu manh
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu lanh dao ((nang xa) OR (nang ma)) hoi. hieu van nang tuc xa thanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu lanh dao ((nang xa) OR (nang ma)) hoi. hieu van nang tuc xa thanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu lanh dao ((nang xa) OR (nang ma)) hoi. hieu van nang tuc xa thanh vai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu lanh dao ((nang xa) OR (nang ma)) hoi. hieu van nang tuc xa thanh vai ((cua tre) or (cua te))*.
