nang xa » nang x, lang xa, nang ma
tinh va » tich va, trinh van, trinh vat
tinh vi » trinh vi, tinh voi, dinh vi
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cau » va cau, ve cac, le cau
ke cau » ket cau

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

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