Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh tai » doanh tai, dinh tai, hanh tai
thuc va » thuc vat, thuc dan, thuc day
hieu ve » hieu va, hieu van
nang ho » nang hoc, nang co, tang ho
ho hoi » hoc hoi, hoa hoi, hoi hoi
ve cam » ve cham, ve cac, va cam
sac ky » sai ky
tuc va » truc va, tuc xa, duc va
tai ve » tai va, tai he, tai le

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sac ky) or (cac ky)) nang ho hoi. hieu ve cam ((tuc va) OR (thuc va)) danh tai ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) nang ho hoi. hieu ve cam ((tuc va) OR (thuc va)) danh tai ve triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (cac ky)) nang ho hoi. hieu ve cam ((tuc va) OR (thuc va)) danh tai ve triet*".
