Perhaps you should try some spelling variations:
ve triet » va trien, su triet
ky dang » ky danh
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
te cao » te bao
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
dan de » dan den, dang de, van de

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

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