Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
lang van » dang van, tang van, hoang van
lang xa » lang ha, dang xay
sach ly » sach y, sach lo, sach ty
hieu ve » hieu va, hieu van
su sach » so sach, vu sach
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
vi su » va su, ve su, ki su

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly ((lang xa) OR (lang van)) hoi. hieu ve cam ((xuc va) or (thuc vat)) hanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly ((lang xa) OR (lang van)) hoi. hieu ve cam ((xuc va) OR (thuc vat)) hanh vi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly ((lang xa) OR (lang van)) hoi. hieu ve cam ((xuc va) or (thuc vat)) hanh vi su triet*".
