Perhaps you should try some spelling variations:
van triet » va triet, van thiet, van trieu
nam thuc » nam thuoc, am thuc, nam thu
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, dam thuc
va hanh » van hanh, va thanh, va danh
sanh y » anh y, hanh y, sach y
sinh y » sinh ly

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

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