Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, thanh san
su triet » su viet, su tien, ve triet
dam thuc » am thuc, dan thuc, nam thuc
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
cam tu » cam thu, nam tu, dam tu

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 ((cam tu) or (dam thuc)) va ((thanh tai) or (doanh tai)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ve ((cam tu) OR (dam thuc)) va ((thanh tai) OR (doanh tai)) su triet.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ve ((cam tu) or (dam thuc)) va ((thanh tai) or (doanh tai)) su triet*.
