Perhaps you should try some spelling variations:
thien van » thi van
su triet » su viet, su tien
cham tuc » nham thuc, pham thuc, tham thuc
van cham » van chat, van tham, va cham
ve triet » va trien
nang xa » nang x, lang xa, nang ma
sach va » sach xa, sach ha, sach dao
sach v » sach y, sach 2, sach vay
tuc va » thuc va, truc va, tuc xa
va dan » ca dan, va dao, va dau
dan vi » doan vi, don vi, dan va

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: toc ((sach v) OR (sach va)) nang xa hoi. thien van cham tuc va dan vi ((su triet) OR (ve triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach v) OR (sach va)) nang xa hoi. thien van cham tuc va dan vi ((su triet) or (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach v) OR (sach va)) nang xa hoi. thien van cham tuc va dan vi ((su triet) or (ve triet))*.
