Perhaps you should try some spelling variations:
thien van » thi van
hanh dai » hanh tai, hanh dao, vanh dai
su triet » su viet, su tien, ve triet
tu sach » thu sach, su sach, te sach
sach ly » sach y, sach lo, sach ty
ly nang » ky nang, ly hang, ly vang
van dau » van dao, phan dau
thuc va » thuc dan, thuc day
xuc va » duc va, tuc va, luc va
dai su » dai sua, dai so, dan su
x hoi » xa hoi, o hoi, x ho

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

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