nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
do cua » doi cua, co cua, de 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 sac ky nang xa hoi. ((hieu ve) or (hieu qua)) cam duc ((van thanh) OR (ban thanh)) do cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. ((hieu ve) OR (hieu qua)) cam duc ((van thanh) OR (ban thanh)) do cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. ((hieu ve) or (hieu qua)) cam duc ((van thanh) OR (ban thanh)) do cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. ((hieu ve) or (hieu qua)) cam duc ((van thanh) OR (ban thanh)) do cua triet*.
