Perhaps you should try some spelling variations:
thuat sach » thuat lanh
thuat san » thuat toan, thuat song, thuat lanh
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hang » van hang, va nang, va lang
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat sach) OR (thuat san)) y nang xa hoi. ((hieu ve) or (hieu qua)) cam xuc va hang va su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (thuat san)) y nang xa hoi. ((hieu ve) OR (hieu qua)) cam xuc va hang va su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) OR (thuat san)) y nang xa hoi. ((hieu ve) or (hieu qua)) cam xuc va hang va su triet".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) OR (thuat san)) y nang xa hoi. ((hieu ve) or (hieu qua)) cam xuc va hang va su triet*.
