Perhaps you should try some spelling variations:
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
duoc va » nuoc va, duoc ma, duong va
hanh di » hanh vi, hanh de, hang di
cua tre » cuu tre, cua triet, dua tren
vu cac » va cac, tu cac, ve cac
ma hoi » mai hoi, xa hoi, ma hoa
ve dat » de dat, va dat, ve dao
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: vu cac ky nang ma hoi. hieu ve dat ((duoc va) or (duc va)) hanh di ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky nang ma hoi. hieu ve dat ((duoc va) OR (duc va)) hanh di ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky nang ma hoi. hieu ve dat ((duoc va) or (duc va)) hanh di ((cua tre) OR (cua te))*".
