Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh, hoc dan, thuc vat
thuc van » thuc vat, thuc va, thuc hanh
hieu ve » hieu va, hieu van
nang ho » nang hoc, nang co, tang ho
ho hoi » hoc hoi, hoa hoi, hoi hoi
sac ky » cac ky
ve cam » ve cham, ve cac, va cam
d cua » de cua, do cua, da cua

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 (sai ky)) nang ho hoi. hieu ve cam ((thuc van) OR (thuc dan)) anh d cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sai ky)) nang ho hoi. hieu ve cam ((thuc van) OR (thuc dan)) anh d cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (sai ky)) nang ho hoi. hieu ve cam ((thuc van) OR (thuc dan)) anh d cua triet*".
