Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
thu sach » thuat sach, thuoc sach, thu hoach
vanh dai » van dai, vanh tai, lanh dao
tu sach » su sach, te sach, tu cach
nang xa » nang x, lang xa, nang ma
van dau » van dao, phan dau
y nang » ky nang, ly nang, v nang
tuc va » thuc va, truc va, tuc xa

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) y nang xa hoi. thien van dau ((tuc va) OR (duc va)) vanh dai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) y nang xa hoi. thien van dau ((tuc va) or (duc va)) vanh dai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) OR (tu sach)) y nang xa hoi. thien van dau ((tuc va) or (duc va)) vanh dai cua triet*.
